Hi tellmewhatulike!- Gee, I've got another customer that is having trouble with the mermaids that also uses proPack and XP, I'm going to have to do some research, and also finally put ProPack on my computer, maybe get a copy of XP, too. A question first though - do all your thumbnails show up in the Mermaid folder, or you you get any shruging guys? I can give you something to try, though, go in the Geometries/Zygote People folder and delete the blmilwom.rsr (not the OBJ), also go into the Geometries/Mermaid folder and delete all the .RSR files. Give that a shot first, sometimes Poser does a mini crash the fist time you open a new figure and writes bad RSRs.
