mouse bleeds over to other monitor and causes game to minimize

Hi, this is a recent issue as this was not the case last time i played about a month ago. But now it seems when im moving around in the game the mouse does not stay on the main monitor but bleeds over to my second monitor which causes the game to minimize when i click.

it happens on all games but i usually play bf3. (battlefield 3)

i did find this

How to lock your mouse inside a game on a dual monitor setup. - A Collection of Essential Guides - Neowin Forums

so i guess it is a somewhat common issue. But i do agree that rather than try to cover it up with more software it would be nice to know why its doing this now and try to fix it.

Has anyone else experienced this and could offer some advise?

thanks

found the solution, if your running DisplayFusion Pro there is a setting that will help you with this..

On the Settings > Functions tab, there's a function called "Lock/Unlock Mouse Cursor to Current Monitor." Just set a key combination on that function, and run it before you start your game

this will surely help until dice fixes the issue as im sure this is a game issue.
