      On my office computer (running 1809 at the time) I decided to try out window snapping, as I’d never used it. I wasn’t impressed so disabled it again. It didn’t disable… every time I move a window around, no matter its position on the screen, the window pops up fullscreen, even on two windows manually placed side-by-side. Moving any windows, even a little nudge,  blows it up fullscreen. It’s really annoying. I got upgraded to 1903 recently on that machine  and the issue persists. I have a triple monitor setup but this only happens on the 1st two screens. The 3rd has its own issues with some programs occasionally popping fullscreen (it’s a 2K with vertical orientation mostly for Dreamweaver work) but usually they stay where I put them in a normal window on that monitor and I can move them without a resize happening.

      Googling it basically brings up multiple posts, all basically saying disable Snap in the mouse options screen from Control Panel. This does nothing and I’ve not found much of anything else by way of a solution. I do run Display Fusion which has a ton of screen options, but nothing I can see regarding window snapping or auto-resizing, so I don’t think that’s involved at all.

      Anyone else run into this issue? If so, have you found a way to resolve it? The only other post I found that claimed to have worked was by someone who did a barebones reinstall, which is not an option.

      Wild guess:
      Take a look at System\Tablet Mode.
      Running full screen is tablet behavior.

      Tablet mode as suggested by PKCano does seem most likely.

      Control Panel Mouse Properties only has an Snap To option for moving the mouse pointer to a default button automatically; nothing about moving windows there.

      But Settings, System, Multitasking is where Windows 10 options live for snapping windows.

      And Display Fusion does have its own options on a Windows Snapping tab:

        Thanks for the tip. Unfortunately, it doesn’t seem to be involved. Tablet mode was already completely disabled, Window Snap in D.F. is not enabled (I had somehow overlooked that but checked), the mouse snap is disabled in Windows properties and I haven’t run across anything else anywhere online related to snapping anything that might explain what it’s doing. I may break down and do a full backup then a repair-reinstall to see if that helps, although the upgrade to 1903 didn’t change anything.

      I’d try modifying the HKEY_CURRENT_USER\Control Panel\Desktop\DockMoving value – setting it to zero should disable snapping entirely.

      A run through the Accessibility settings might turn up something.
      Funny thing, that Accessibility icon is right by shutdown on the login screen.

      Thanks for all the suggestions folks. Sadly, nothing worked. I’m stumped.

      I guess I’ll either put up with it or do an in-place reinstall to keep nearly everything that’s non-system intact and see if that works. I don’t want to do a fresh one since some programs are Giveaway-of- the-day types with no reinstall functionality. My backups are all since this happened a while back so they’ll all have the same issue (I put up with if for a couple months until I got annoyed enough to try and do something about it).

        I think you could/should exit from Display Fusion by right-clicking the tray icon and try running without that for a short while. That way you’d know whether it’s connected with that or Windows 10.

      No effect, so it’s something in Win 10 then. Thanks for the suggestion.
