Flashing Intro movies and game screen

[jsmithhtml]

Just in case anyone else runs into this issue.

When running the game I sometimes get flashing during the intro movie and in-game. It is really obvious and looks like there is a refresh problem. I have an ATI Radeon HD 4870 X2 running on Vista x32

It turns out if my machine enters sleep mode and then I run the game the video gets all corrupted. If you reboot before running the game after the machine exits sleep mode the game works fine.
