Recently, NirSoft came out with a new app called AppCrashView
It works on Windows Vista and Windows 7, since before Vista, crash logs weren't saved in .wer files.
Anyways, I started it up and it contained a log of Nexuiz crashing a couple of weeks ago. Maybe this info could be usefull to the developpers?
