If what is happening for you is the same thing that's been going on over here, it's not Keyclone. I've had these crashes happen when WoW is open in windowed mode, both maximized and not. The problem seems to happen when you tab out, or in my case, look at a few web pages on a 2nd screen while loading in areas. Sometimes it happens even when not looking at teh pron. I'm 94.553% sure it has something to do with WoW and not Keyclone.
