I had one game lock-up when exiting the game. I needed to do a Cntr/Alt/Del to end the game.

I have had two instances of the graphics corrupting when the game auto saves. On both instances however, Alt/Tab the game to the desktop and back seemed to fix it.

I cannot place spies, the place agent button does not ever work for me no matter what type of improvment I try to place one on.

System:
AMD 64 X2 3800+
ASRock Dual 939 board
1GB Muskin RAM
Geforce 6900 Ultra (Latest Nvidia drivers)
Creative Audigy 2 (Current Drivers)
