GREEDY Game is GREEDY

Stop me if you've heard this one before: You're playing CosBreak fullscreen and use Alt+Tab to swap to another program, only to have CosBreak throw a fit and not let you do pull the other program to the front.
Don't get me wrong, unlike other games I have played, CosBreak does an in-credibly wonderful job at keeping the mouse inside Windowed mode during actual involving gameplay, but this may become a constant point of contention and rage to some who enjoy Fullscreening.

Gets like that to me. Only one other game I've played does that too and it's S4 League. Once in a blue moon, I can actually go from CB to my Desktop but I can't intentionally do it.
