Summary: From time to time, WindowServer crashes spontaneously after a keystroke. Steps to Reproduce: This issue cannot be deterministically reproduced. Press a key (if I'm not mistaken, it has always happened in a Carbon/PPC application - Eudora) Expected Results: The keystroke is processed normally Actual Results: WindowServer crashes, taking all user processes with it Regression: It has happened three times for me (twice in November, once today), totally randomly. I can't associate any specific circumstances with it except that I believe I always had Eudora frontmost, but that could also be because that's what I use most. The fact that the problem didn't happen before November doesn't mean anything - I only upgraded from a Powerbook with Tiger to a MBP with Leopard in November. Notes: Stack trace of the crashing thread has always been identical, so I only provide one.

Still happens with Eudora
I must have changed some System Preference or installed some software that has now triggered this on my Snow Leopard 10.6.0 MacBook Pro. Based on lots of web posts and blogs, the issue is Rosetta and a PPC executable (Eudora and Excel are most often mentioned). Typing a character triggers it.

I'm now getting one or two crashes a day - this will force me to abandon Eudora after decades of use. I have no idea of what change I did, so no idea how to revert...
