For yoy Orio and also for Joerg, I have installed Vue "from scratch" on a computer whith Windows Millenium (PIII, 850, 256 RAM) It was a virgin place where Vue never has been. I have done exactly : Vue 4, Vue full update 05, Vue incremential update 06. I have imported all sorts of OBJ files from Poser, free stuff, things I have created outside Vue. All, absolutely all works fine. I can rotate it, move, every thing without problem. Also I think there may be an interference (but I'm not a technician) somewhere on your computer? Now I'm gone to uninstall again, because this computer only has a 10 MB HD, nearly full now. Guitta
