If you still see the issue without any known conditions, you might want to send the information to Microsoft when the crash prompts you to send the information to Microsoft. Later, I can retrieve the information from Microsoft.
OK, I’ll do that.

Try App Crash View, which should give you crash reports:

Unfortunately, it does not work in WinXP.
