  • I wasn't expecting this to work with Windows 10 - But it does, and works well. Thanks!

  • Does exactly what I needed. Unobtrusive. Easy to use. Probably could stand to be better advertised since it took a few false starts looking at much more clumsy alternatives before I found this perfect little add on.

  • I found this because I was having a problem with the game Dead Island. I was contently clicking out the the game even while it was full screen. For whatever reason the mouse continued to move around the desktop while in game. This app fixed my issue by not allowing the cursor to move to my second monitor. Now I can continue playing knowing that I'm not going to click to my second monitor while slashing a zombies. Here are a couple of suggestions on changes: 1. I would like to see custom key binding so that you can avoid incompatibilities due to <CRTL>+` already being mapped. 2. It doesn't look like the app work when it is minimized to the tray or not the active window. Either that or I'm just running into some bug on my laptop that locks me to a screen after sav&close or after I move the window to the other monitor. 3. I would also like to see it work with window snapping (<win>+<arrow>) 4. I would also like to see it work with the keyboard functions win DisplayFustion. This is the same as item #3 but were not talking about OS key bindings but an dual monitor application that does similar functionality. That being said this app does what it is says it does and it will help me out with some game titles.

  • Do what it said it does. However, it doesn't work with the auto docking feature in Windows 7. When I drag a window to the right expecting it to auto dock to the right, the window still goes beyond the primary display.

  • You really need to add a Shortcut Specify Feature. Especially "CTRL + ~" is critical on different keyboard layouts. I can't use it with my german QWERTZ-Layout. But the tool itself is awesome. just did what its meant to do.
