Well, I'm lucky I don't have crashing problems with scenes. There are still a few things that lock up Carrara...I think version 4 has finally stopped dropping dead during a modelling session. Bob Stockwell has been great about replies. When I have a question about price, or when I was innundated by ebots, he got right back to me. There are elements in CP4, though, that makes me wonder if they even listened to their beta testers. Or even bothered to hire any.
