Had the same problem. Solution that works for me is to load the 3rd (4th, 5th, etc) figure/model, render, Save As a .pz3 file and low-res .jpg (25%, which I delete later). Close Poser completely and then reload Poser. Import the .pz3 file and all the invisible body parts are now visible. Works only with Win 2000 Pro/Server and NT. Win 9x requires a complete restart of the O/S. Seems there are "disagreements" on memory usage sometimes between Poser and W2K, NT, and 9x. Just shutting down Power will clear up the memory dispute in W2K and NT, but 9x requires a complete restart.
