When playing the game on my wife's laptop the screen will suddenly go black as if it has crashed. Hitting the power button I get "resuming windows" as if it had gone into hibernate. Upon resuming the game is still running just as it was. After this it will flicker like the screen is being turned on and off.

I've experienced similar things on my desktop but not nearly as frequent or bad.
Both are Win7, 64 laptop, 32 desktop.

Both are running 1.0.4.
