dawn; That is one of those' It shouldn't, but...' ideas. If you have a firewall program, set it to block Vue from accessing the internet, and give it a try. Since it did this only when the camera moved, that leans more towards being an internal Vue issue. You might want to re-enable the draw background thread and see what happens, as that process handles the window redraw. If things start crashing immediately, then there is something with either the video, or Vue's interfacing to it going on. A clean reinstall of Vue -may- correct it, then. And gill, I don't think that anyone has ever said that Vue (either flavor) lacks bugs and issues. But the hard truth is that the days of it being 'only X of Y' are pretty much over. There is just too much integration between OS and apps, and too much interdependency between hardware and software. If it is all Vue's fault, then there isn't a lot that can be done by anyone but e-on (and there should be large numbers of people having the problem). However, I have dealt with too many 'My Nifty New Proggie is a POS because it don't Work on my megabox waaaaaaaaaah!!!!! (profanity string of your choice)' maintenance tasks, only to find it wasn't the accused program, but an undetected hardware issue, and OS corruption, or configuration issue that was really to blame. A small core of people are having trouble; not a large swath. That tends to suggest a config issue. That doesn't mean there isn't a bad bit of code in the suspect app; there almost has to be for there to be a configuation issue. It takes all the elements to create the spell. But we can't fix that. What we can do is try and isolate just -what- configurations are giving people fits; there has to be some common factors there. And that doesn't include the fact that you can have a bum stick of RAM, with a single bit at the top of the stack that is weak, and so long as you run apps that never address that area, you will never know it. If dawn was having a CTD, that is what I would have suggested first, as Vue simply shuts down when it runs out of physical memory. Every potential issue that's eliminated narrows the field of investigation. And CG renderers like Vue, Poser, Cinema, and so on, stress a system more than just about any other app, even most games.
