Do you have crash when closing a project window ? Or loading another Skp file ? I have such crashes, it's minor for me, but since month I was sick about. I send a mail to Google SketchUp team, and they send me a procedure to try to fix it. I will try these days and tell you about.

Hi, Have you seen this: http://forums.sketchucation.com/viewtopic.php?f=79&t=34043

Yes I agree with you Edson. Those are some helpful hints that I though about giving but he only stated problems with opening and closing files mainly.
