I have been getting a regular crash using apprentice. It will work fine for a period of time, sometimes even a few hours straight when suddenly it will crash when I hit any button or mouse click. This has happened several times and I can't seem to narrow down a repeatable issue.

I have tried in both 9.5.241 and 9.5.350 with no difference. Houdini will shut down and save the crashlog. If I immediately start Houdini back up and try to go back to work on what I am doing it will crash again immediately. Only a restart of my machine seems to fix the problem.

I am using Vista 32 and a Nvidia 8500 GT graphics card.

I have this same error in the crashlog everytime it happens:

Crash report from Slade; Houdini Master Version 9.5.241
Traceback from Sun Feb 01 14:08:26 2009
Caught signal 11
+0x071605a8

Any help on what might be causing this would be much appreciated.
