Before I bother support about this, I wanted to ask if this has happened to anyone else yet: I have a 64bit Win 7 system. When playing this game, the mouse locks up randomly. This happens most often to me while in the options menu, but it has also happened while playing the game itself.

And once that happens, I'm utterly screwed. I can't play the game, because no mouselook. I can't navigate the menus, because the cursor is locked in place. I can't use the Windows key. I can't Alt-Tab out of the game. When I Ctrl-Alt-Del out of the game, the cursor is still locked in place. After the game has been forced to shut down, I'm greeted with a black screen, the mouse still locked in place. Only way to "fix" things is to restart my PC.
