Wow! That's interesting, les. I never noticed that before. I very seldom enable 'show lights' in the editor, even though I use it all the time for everything else. I tried it and no matter what I did, I couldn't get poser (P4) to hang. Not that I doubt you. I was just trying to break it. I did end up with about 50 million lights. LOL. Well, thanks for the info. I'll put a note in the help file about it. With poser, it definitely pays to be paranoid. mac
