[Xquartz-dev] SwitchCoreKeyboard crash possible fix

Fri Aug 22 04:50:08 PDT 2008

Sweet! That means this is most likely fixed now.  The debugging info I  
got from someone else pointed me to something that should only happen  
on a system with an attached tablet (and that's probably why I never  
saw the bug).

Please test out that binary I mentioned and let me know how it  
works... I'll probably put out another rc in the next couple days.

Is anyone seeing the NewCurrentScreen crash?  Crash reports are being  
sent into apple with 2.3.0 (which included what I thought would fix  
the problem)... unfortunately I have no contact info for anyone  
actually seeing this crash (either reliably or sporadically).  If you  
have been seeing crashes in NewCurrentScreen, please let me know.

Thanks,
Jeremy
