Thanks, I thought I'd ask in case somebody else might have had the same setup as me in the display properties. I'll try changing various settings. Btw, for anyone else who sees this and may have a clue, I'm on a pc, XP Service pack 2, poser 6 has the SR 1 installed and all the other scripts are running smoothly. And yes, I bought the OM for pc - I know it's obvious but it was the first question hubby asked :)
