Thank you, Steve, that might be it. I used to have Painter 3D installed but canned it, since it's not worth the time. Unfortunately, there is no Painter 3D-uninstall on the CD, so I just threw the whole caboodle in the bin just like that. But now the jackpot question: How do I know that I have trashy .ARP's left on the machine, and how do I get rid of them? regards D.
