One of poser's nastier habits is saving half a file for no apparent reason. Someone else here had this happen recently and sent me the .pz3 to look at. I discovered it had saved about 2/3 of the file and suddenly cut off in the middle of a character. Go figure! The safest way is to save different versions of a file. I use A and B versions, alternating the saves every 5 minutes or so. mac
