Recently formatted my system, and now running into an odd problem.
Whenever playing a game, when I alt-tab out of the game, I can't bring the game back up. I click on the game tab on the start menu, nothing happens. I can't bring it back up using Alt-Tab either. Sometimes I get lucky and can get it back up if I click a lot. Otherwise, I have to close the game and start over.
This seems to happen with all games running full screen. I haven't tested them in window mode though, but would rather not play any game in window mode. Also it seems to be only games. Not any other applications.
I have no idea what could be causing my games to get stuck once I alt-tab. Any help is greatly appreciated on this one.
