Thanks for the responses. I have sent them files that I thought were corrupt, but they couldn't reproduce the crash.
ptc-408694 - that's and interesting thought. I do have Creo 2.0 (M030) as well as Elements/WF5 (M170). I don't remember if I installed Elements because 2.0 was crashing, or the crashing happened after I installed Elements. I will try and figure that out
