--- Comment #35 from Dan Kegel dank@kegel.com 2008-02-21 13:19:54 --- Since the original problem was with Cinema 4D, I think we can close this bug. Can somebody open a new one specifically for the thread problem with WoW?
I agree this is probably a case of WoW having a fragile multithreading scheme that Wine screws up on somehow.
