Civilization IV and fusion

I have fusion 2.0 and just got Civ IV. I updated both Direct X and the games most recent patch, but every time I open the screen it flashes repeatedly between Civ IV and windows, so I cant play the game. Tried calling their tech support and they had no idea what I was talking about. They didnt even know about fusion and a mac.....

Looked on the internet, Civ IV websites and did a search here, but didnt find anything. What do you recommend????

Did you check the settings in Fusion? You need to give it both processors, lots of ram, and DirectX.
