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.
