Yesterday I had a weird problem where my game would go to the desktop. It didn't crash, it just acted the same way as if I had hit alt-tab. Other than that, the only crashing problem I've had is when I quit the the game it will lock up 8 out of 10 times. I think this is because I switched to a Mac using bootcamp, because I didn't have this problem on my old PC.
Actually this has happened to me a couple times. Nothing that really bothers me because it happens so rarely and when it does it usually only does it once for me but yeah it just minimizes itself out of the blue heh. Thought it was just me.
