Um ok silly question... Have you rebooted? Mind you, something similar happened to me after Poser got stuck on lights, but it was only the pz3 I had open at the time. Are all your pz3's in the same place? If yes, try moving them. Empty your windows temp folder (always a good idea anyway, lots of rubbish accumulates there) Empty recycle bin. Rename some pz3's that you haven't opened yet to something else and try. (Before that I would pull a lot onto CD first, in case it wipes them clean) I'm just blindly stabbing at stuff here, I don't really know what's causing it. :( But I figured every little helps.
