Has anyone found a solution for PoserPro and Open GL preview?  Apparently my graphics card, GeForce 8800GTS or Windows Vista Ulitimate won't support it and I'm forced to use the Spree preview.  I've got the latest drivers.  My computer has plenty of beef to run PoserPro and generally I'm pleased with the exception of the Open GL issue and the occasional crash.

My system is:
Motherboard  Asus Maximus Formula Special Edition
CPU   Intel Core 2 Extreme QX9650 Quad-Core (Penryn)
Ram   4 x OCZ DDR2-800 Reaper 2048MB w/ Heatpipe Cooling

CPU Cooling  Koolance CPU Waterblock CPU-330
Liquid Cooling:  Video Koolance GeForce 8800GT/GTS Waterblock
ATech 28-in-1 USB 2.0 Internal/External Card Reader (black)
Monitor    SAMSUNG SyncMaster 305T 30 inch LCD Monitor
Speakers   Logitech X-240
Operating System Windows Vista Ultimate 64-bit SP1

Now if someone could come up with a solution in Vista for the open GL preview, I would be in Poser heaven with Poser Pro.  Also, has anyone else had stablity problems (sudden blank screen) with Poser Pro?  I'm not sure, but I think it is a Vista problem.

I found my real skin shaders did not work unless placed in the same directory as the Poser version running.  For example, I run Poser Pro but take objects from Poser7.  I could not use python scripts, at least the realism shaders, from the Poser7 directory, but they worked if I installed them in the Poser Pro directory.  Also I found that when in the Vista operating system you have to have UAC turned off for some of the realism shaders.  Apparently no matter where you install them (for example I have all Poser stuff on my D: drive) some scripts want to access the C: drive and UAC denies access.  I don't know if this helps, but it has been my experience so far.
