I had this running well on Snow Leopard program, upgraded to Lion OSX HAWX ran fine no problem. I upgraded to 11.02 I was getting blank screens and the following errors Saved dumped file to C:\programs files\ubisoft\Tom Clancy's H.A.W.X\HAWX.exe.dmp. I had to down grade to 10.3. I can confirm this works ok, I had to use the Run Command to get it to work but it works and I'm happy once again.
I would say stick to 10.3 for HAWX other wise it will not work on 11.02 of crossover. Hopefully this will be fixed in the next updated version.
Also I would like to thank Andrew too for suggesting that I downgrade back to 10.3.
