Along NEUROcYBER'Strain of thought, I had a floppy-drive short bunout my old Creative Labs Grahics blaster and replaced it with an ATI Rage 128. Poser got REALLY hinky on me...it would render and display OK, but but when I would save a figure oor prop, there would be a blank space for the thumbnail (not even the "shruggy guy"!!!) I went absolutely crazy with de- & re-installs until I replaced my card with a Hercules (it was dirt cheap!) and viola, everything was fine! So I'd say it's your graphics card too...Get a cheap one (in the $75-100 Range)...and stay away from ATI!
