I'm playing assassin's creed now and that causes it do to that, when I alt+tab out of the game, the game goes from full screen to windowed and it causes some annoying problems.
Then theres a painting program I'm using also, it causes the borders around that problem to be messed up looking if I don't go properties>disable desktop something...
I already know the program is not compatible with aero...pretty obvious from the pop up message it gives you and the theme changing on you. I just dont get why the hell it has to do that. They gotta fix it so it doesn't cause any problems with anything...this is just retarded
