Carlton,
That was not an accusation. Sorry if you think it was. It was not aimed at you, just  troubleshooting issues in general. Just because people don't complain on the forums, doesn't mean they don't have a problem. Sometimes people are also quick to assume bugs that's all. I am just trying to help. You have to be dead specific and provide the exact circumstances. I don't have several of the files or plugins mentioned. Don't have David either, like I said so I can't really check certain things.That's why they ask for files, which is the best way to tell if everything is the same. Everything is a variable. I don't dispute it is a problem. I know it is frustrating to deal with this stuff, but I would report them. They have been very nice about responding to bug reports.

That crash log may have been what the person meant, It was a discussion about having an internal error reporting log like D|S. Crash logs don't help, but so much. I get plenty of issues or lack of responses w/ little or no real feedback, I really don't like not having anything to get useful feedback from. Who does?  I have had carrara throw me completely out and close several times with trees. I don't doubt there are some memory efficiency issues, however, with me I have to be fair w/ the current amount of ram. Have you monitored you ram usage during any of these slow, but functional scenes to see what it is doing?

No need to think outside the box....
    Just make it invisible.
