One thing that I have noticed, and I'm not saying that this is your particular problem Gaussian it's just an observation, is that when Vue Pro imports an object from another program (such as Poser 5 in my case) it takes a LONG TIME to do the import. Vue Pro is actually "rendering" a low quality version of the object while this is taking place. It uses this version to display the object in OpenGL mode. The "rendering" is why it takes so long. I haven't seen a setting that will let you disable this. Perhaps some people are taking this long import time and thinking their system is locked up since it does take a lot of system resources and it seems locked up. I thought this at first but I waited and found my system wasn't locked up after all.
