Won't run full screen

[Orov]

Last night when I installed the game I had it running full screen nicely. Today it defaulted to windowed mode (no big deal) but when I try to make it full screen it crashes and even messes up the gamma on my system after its gone. I HATE playing games in windowed mode. Also I'm having the same problem as a few other people: when I click certain places on the screen sometimes it minimizes the game for me. Thoughts?

Thanks!
