[Wine] Program runs in Xfce, but not KDE?

I play a game called Ultima Online..
the client runs 100% just fine when im using xfce but crashes when im using kde?

nothing else has changed on the system. i do use kdm ive tried gdm as well.

any ideas?

i can just log out, switch session to xfce and play the game with no issues.. 
but i like kde..
