I hope someone can help with a small problem I'm having with Vue Pioneer as I'm trying it out before upgrading to a better version.  Program fires up fine but, even without loading anything, as soon as I touch any of the camera controls (move, pan, etc.) my whole display breaks up into juddering bars that stop when I stop moving the camera.

I'm running XP on a dual-core Athlon with 4Mb of Ram and an ATI Radeon card with the latest software driver upgrades.  I don't have this problem with any other graphics intensive or CAD program.  I notice that the program always starts up in OpenGL software mode - it won't accept the hardware accelerated option.

Has anybody else experienced this and, if so, how did you overcome it?
