Judging by the shape of the upper window bar, you're using windows vista/7? Try changing compatibility mode to XP, can't guarantee it'll help but it was a first thought that came through my mind (probably because I'm a Vista hater xD )
I'd also suggest updating your graph card drivers to the latest version if you haven't done so already.
