Non Stick Mouse for Windows 10 & 11

Use this application to disable or bypass the sticky corners in Windows 10 & 11 for dual displays or multiple monitors. What it does is hop the mouse over the sticking corners, as well as the screen edges when moving windows. Thus it allows the dragging of windows through screens without your mouse getting hijacked by the Snap Assist.

The Hot Corners and Snap Assist still work, but now only when you want them to.

Note: A user has reported this app got falsely flagged as a game cheating app – which may cause issues for any Blizzard or Activision games, such as CoD.

Latest Version released on 20th of February, 2025.

And for your peace of mind the full source code written in Delphi, 3 files on GitHub.

This application does not read or write to any drive, it does not access the registry or connect to the Internet.
I am only sharing this as I took the time to write it and I notice many people are annoyed by these Microsoft “features”.

It hides its window – so terminate it use the Task Manager. It is not designed to be overly clever, it does not have a notification tray icon.
If you want it to run on start up make a shortcut to where you have saved it in the start up folder, or use the installer!

If it is does not work at all please let me know and I will try to fix it when I have time.

It won’t fire when the active/topmost window belongs to a process which is running with privileges elevated higher than what NonStickMouse itself is running with.

In an effort to minimise misfires this take parameters of when to fire: –
“corners” – only fires when in a corner (thus dragging a window across screens will stick).
“lag” – a delay between firing the hop. The default is 500 milliseconds but that can be overwritten by putting a value after the word lag.

These parameters can be affected by being embedded in the filename itself, thus renaming “NonStickMouse.exe” to “NSM_Corners_Lag_200.exe” will activate both, with a delay of 200ms.  Use as required.

Subsequently I have also developed a debug version: –
(Consequently, due to the mindless stupidity of virus-scanners, of which I’m not even going to bother to try to counter, I took it off my site.  If you need this app to help diagnose your issue please let me know and I can make it available for you.)
This has a User Interface showing the screen dimensions and offsets of each monitor, the mouse tracking, and the values it was at when the last hop was fired. This application will also hop the mouse so for complete accuracy please terminate NonStickMouse.exe when using it.

You may choose to compile this yourself for your own sense of security – in which case follow the instructions here: –

Non Stick Mouse for Windows 10 & 11 — 671 Comments

  1. Windows 10 Pro 64-bit, Version 21H1, build 19043.928

    Nonstickmouse fails (gets stuck in an upper corner), on a two-monitor setup, whenever the Task Manager is open.
    Closing Task Manager solves this problem.

    But I have Task Manager open a lot. Is this a known bug?

    • Yes. That’s the bit referenced in bold saying “It won’t fire when the active/topmost window belongs to a process which is running with privileges elevated higher than what NonStickMouse itself is running with.”

      The reason being if an app could somehow control another app which has higher privilege is it could re-execute itself as admin, then automate clicking the Yes button!

      If you’re happy to run NSM as admin so it can function when higher privilege apps are in the foreground you can do so with the Task Scheduler as detailed here https://superuser.com/a/770439/190255 (which is what I do).

      Let me know if you get stuck.

    • I kid you not – it still catches me extremely rarely. The poll is set to 100ms – which means if my quick gamer hands pre-fire … oops! But yup, your windows should be a lot safer now – if you manage to beat the timer you can tweak it to a lower value (uses a bit more CPU though).
      Cheers 🙂

  32. Hi Jonathan. Thank you for this fix to an issue windows should clearly fix themselves. I have one question however – I am scared to install it as you said that “A user has reported this app got falsely flagged as a game cheating app – which may cause issues for any Blizzard or Activision games”.

    I don’t want to get banned from these services, do you have any more information on this front?

    Reply ↓

    • Wow, I forgot I activated ads on this site (was playing with adwords) let me know if it’s annoying!!

      Anyway, the only time this happened is referenced here: –
      https://www.jawfin.net/nsm/comment-page-5/#comment-24587
      And the 9 comments below.

      As Blizzard seem to have a consumer policy of ignoring their consumers I don’t know where it went from there.
      But this has been the only reported time – even still I just cannot answer how Blizzard are behaving these days.
      I’m very sorry that I cannot answer definitely.

  33. you are a lifesaver! I have been using this for 1 year and, still, this is my second favorite program(I’m sorry, number one is Everything).
    I already donated back then but want to donate again so have some.
    it ain’t much but I want to give you an appreciation.
    thank you again

  34. Been using NSM for a long while now. I actually have two copies: one user and one administrator. The user one I use all the time and it does exactly what I need. The administrator one helps out when I’m running Visual Studio as an admin so I still get the NSM experience when the focus is on an admin-layer application.

    NSM makes Windows 10 feel fluid across multiple monitors; I strongly dislike working without it. Donation sent. Thanks Jonathan!

    • Thank you very much 🙂

      Sorry for the delay in reply, I was out of town!
      You shouldn’t need to run 2 versions if the administrator one is always running. If you’re running that by hand and prefer it to run automatically you can use the task scheduler to have an app run on user login with administrator privileges.

      Cheers
      Jonathan

  35. I really really want to use your software here, but I noticed that both the exe and the installer are flagged by several AV’s on VirusTotal now… is there anyway you could look into this?

    Thank you for making this fix, it works GREAT!!

  41. Hi Jonathan, I tried your tool on Windows 11 but it doesn’t seem to work. Do you plan a release for Windows 11?

    Reply ↓

    • It should work the same for Win 11. I don’t have it running here though, as a programmer I prefer to use an OS which works for me (joke – kinda), but I will need to move up one day, only because my clients have.

      Nevertheless, it should work the same – I know I have used it on other Win11 multi-display machines.
      My thinking is get the debug version and please post a screen shot of it. https://jawfin.net/download/NSMDebug.zip

      Note that some AVs don’t like this – which is rather incredible, its the exact same code as nsm itself only with a visual interface. In other words, AVs are fine if the app is invisible and works in secret but has an issue if it shows the user exactly what it’s doing! In short, it’s not a problem if you don’t want to use it, I’m just highlighting another aspect of AV stupidity (these comments are full of those!).

  42. Thank you for replying so fast. I guess I used an outdated version as I simply copied the file from my old laptop instead of downloading your most current version. Now it works. Thank you for this lightweight helper!

    PS: The text “Latest Version released on 15th of June, 2020.” on top of this page links to your solitaire page, not to the NSM tool. You should probably fix that?!

    Reply ↓

    • Probably yea!

      And why it wasn’t working is that older version wasn’t DPI aware, like the pixels per inch (which is a thing) is different to the resolution (width & height) – so can have same resolution but a different number of pixels, or more precisely dots, which are scaled per pixel – thus throwing out the math.

      Sorry if I am explaining the obvious (albeit poorly), but someone else may stumble on this and it could help them!

  43. Thank you so much. I never experienced sticky corners until I got myself a new monitor, but installing your software solved the problem.

    Reply ↓

    • Oui, n’hésitez pas à l’utiliser partout où Windows est utilisé – à mon avis, ce serait un crime de facturer la correction d’un bug que Microsoft ne fera pas. Vous avez déjà assez payé !

  46. Love the program. Saved me from lots of frustration.

    Was just checking to make sure I have the latest version, and I saw on the GitHub page that you reference some command line options. Can you give explanations of what options are available, and what they do?

    I also have a question about “bottom” corners. The app works great for the top corners in a multi-monitor system, but what about the bottom corners if the monitors have different resolutions or if some of them are in portrait (vertical) mode instead of landscape (horizontal)?

    For example, right now I have three (3) monitors all in horizontal mode, but the resolutions are different as listed below. The center monitor is a new 40″ Dell monitor to replace an old 27″ that was having serious burn-in issues. The old 27″ had a resolution of 2560 x 1440, so everything lined up perfectly. However, with the new monitor, everything works great for the top corners, but the bottom corners are not aligned and I’m constantly having to move the mouse up when moving from the center monitor to either the left or right monitors.
    – Center: 5120 x 2160
    – Left/Right: 2560 x 1440

    To save desk space, I’m thinking about rotating the left/right monitors to Portrait mode, which might let me move the center monitor forward some so can turn off scaling, if my aging eyes read things clearly. Even with glasses, the native resolution is a bit small.

    Any thoughts on how to handle the bottom corners?

    Thanks,

    David

    • Thanks for the kind regards 🙂

      The commandline arguments currently are: –

      lag [n] ; where n is the milliseconds between checks of mouse position. Default is 500 (half a second).

      corners ; if this parameter is found then it will only attempt to hop the mouse in the corners only. Otherwise it will do it along the whole edge, which is needed for moving windows between screens.

      Ok so, with those bottom corners. This app was designed to move the mouse on the same latitude when otherwise it would get jammed. But this isn’t the case if its at Y = 2500 on monitor 1 and you move it right to the next monitor which only has a height of 2000 – it won’t move there, you still need to lift it up. A custom build could be made with a slipzone where it can see the next monitor isn’t deep enough so it lowers the Y of the mouse to the height of that monitor so it can go across.

      I’ve updated the source code on github, but I don’t think it’s changed. Nevertheless I’ll recompile with the latest version of Delphi I have here and upload. I’ll make a separate post for that once done.

      Reply ↓

      • Thanks for the info on the command line arguments.

        If I understand right, the custom build would have to know the resolution of each monitor, and their orientation, in order to calculate the “bottom” corners. Which could work, but doesn’t allow any flexibility to change orientation? Or would you be able to calculate the “slipzone” dynamically? I’m a bit OCD, so not having the same vertical resolution on all three monitors is driving me crazy. To optimize my desk space, I’m thinking about putting the side monitors in portrait mode, and I’m even thinking about not lining up the either the physical top or bottom of the monitor, which really throws off the “corner” calculations.

        Does the app take in to account things that GPU drivers can do like “SuperResolution” and the system scaling when it does its DPI calculations? For example, I could use the SuperResolution feature of my GPU for my left/right monitors to make them think they are 3840 x 2160 so that the vertical resolution matches the center monitor. The math on all this really give me a headache. I don’t know how you do it.

        • It doesn’t look at orientation, it just relies on that being handled by windows, so it always works off width & height where windows will flip those internally for portrait.

          The app checks what monitor the mouse is on https://github.com/Jawfin/nsm/blob/master/uNSM.pas#L232

          It gets the information of that monitor – its X & Y offsets from the origin and its width & height https://github.com/Jawfin/nsm/blob/master/uNSM.pas#L137

          It checks if its in a corner, and if so and the previous mouse position was somewhere else on that same monitor (meaning it must have moved to a corner from within the screen) it then checks if it continued to move in that direction would it be on a new monitor or just stay put.

          So simple example, 2 screens 800 x 600, mouse was at 790 x 0 (top edge near the right), then next check [500 ms later] its at 799 x 0 (moved right, now in top right corner). We have a second monitor, exactly to the right, so X offset is 800, width then being 800 -> 1599 (height 600). If the coordinate 800 x 0 is legitimate then NSM will move the mouse there https://github.com/Jawfin/nsm/blob/master/uNSM.pas#L245

          Now NSM doesn’t need to know *anything* about that new monitor, just that Windows says 800 x 0 is a legitimate cursor position, regardless of what monitor its on, it’ll just move it there.

          So all the app needs to know is the previous location of the mouse, the current location, whether its an edge or corner, and if so moving more in that direction is possible (ergo must be another screen there) then move it.

          If that right monitor was dropped by 100 pixels, the location 800 x 0 is no longer legitimate so it just won’t move. Have a play with the debug version and see the current monitor, mouse X & Y, and triggered hops activating: https://jawfin.net/download/NSMDebug.zip
          It’ll trigger AVs probably, because they are stupid. Also don’t run the real NSM or else it’ll grab the hops before the debug version does!

          With scaling and DPI stuff, its all handled before I do any work, all scaling are converted before that get monitor and mouse location info (the first github link) so the coordinates should just work and be scaled and same unit for comparisons.

          Hopefully amongst this I’ve answered your questions, but if not please let me know what to clarify.
