Everytime I start up Poser 5, the preview window in the "Pose" room is gone. I can preview my figure in the "Materials" room, but I can't pose my figure. I've reinstalled repeatedly and it works correctly for a while, then it does it again. If this is a known bug, someone please let me know. If anyone else is having the same problem but still hasn't figured it out, let me know also so we can see what's common.
