Limit mouse and windows from going to second monitor?

[UserNameInvalid]

I am using 2 monitor setup and second screen used to play full screen video from YouTube with auto play = on, so don't really need to move mouse on second screen more than once an hour to switch new video etc.


However working with two screens is annoying in a way when mouse and application windows are jumping to second monitor where i don't need them because its used for full screen video playback only.


When in two monitor mode:

1. How to limit mouse to "main display" (green on image)?
2. How to limit apps from going off "main display" (green on image)?
