Without steps to reproduce this, we’ll at least need a crash dump to look at. I can’t seen any reported crashes from your eMail address. Please always send those in.

I’m afraid that one doesn’t help but is a sign that there should have been a crash reporter. When Rhino crashes and it’s caught, two files are created on the desktop. Then the crash reporter should pop up. When the crash reported is closed, the dmp file is automatically deleted.
Since it sounds like you are frequently crashing, please try to crash it once again and look out for the crash reporter.
