I've noticed lately that some of my .pz3 files have been losing content. At first, it only happened if P6 locked up and I closed it with ctl+alt+del. When I reopened the file, most of the content was missing (i.e. lights, textures, and some figures). But now its happening with files that I normally save and close. I open them up and they show up in wireframe mode, no lights, very few if any textures, and some of the figures are missing. Is this happening to anyone else? I have 1 GB RAM and a 1.8 MHz P4 processor and have SR1 installed.
