I'm running COH under CrossOver Games 7.1.1.
I have 2 screens on this system. When I launch COH it works and I click "Next' and I get "Loading" and that's the last I get. One screen turns white, the other screen turns black. The game loads as I can hear the audio start up, but I have no graphical interaction.
If I go into system preferences > displays and click "Mirror Displays" and try again the game loads. But I have the same image on both screens.
Seems like a pretty big bug to me. Works with one screen but fails with two.
