Thanks everybody, and I will try every suggestion. This is a strange mystery. Still investigating. It was a fairly simple character with nothing else in the scene but a box used as a wall, and some Maya studio hair. I did upgrade to Windows XP last month, and had to reinstall Poser. No real problems with that yet. I have tried spawning a morph target for any faces I create as one sneaky way of saving the face. I did nothing special with the body. That seemed to have fixed it for today, unless the problem went away by itself. I lost every character I created on Saturday.
