I'm on the verge of a totally new PPP install. I had the bright idea of doing a search and destroy of rsr files in the Library folders. Of course there were many png files to replace the rsrs.. They were just waiting to go. But many pngs were not there. All the stuff I had installed into PPP was copied over from the Poser installation. And all that stuff was copied from CD's where it was stored. So who knows, maybe that copy from CD caused something wacky on the read-only attribute stuff? I repeatedly removed the read-only attribute, only to find everything marked read-only the next time I check. Whoopie.
