I've been trying to get BK working for a long time now, hoping each crossover update would fix whatever the problem is.
It installs fine, loads up a huge database and at first glance looks like it's working. However, I've figured out a way by clicking on just the right sequence of things to have it lock up in such a way that trying to exit the Edit window or switch individual won't work and will just play the os bump sound. I've enabled logging and have a bunch of messages like those when it happens...

fixme:win:LockWindowUpdate (0x101ea), partial stub!
fixme:win:LockWindowUpdate (0x0), partial stub!
Any help appreciated.
