Yup, I have both installed into my poser partition on my desktop, I've got the p4 library linked into my p5 library, and with the exception of P5 stuff my P4 libraries is where everything still goes, it's simply more stable and more usable. I want to create images, I don't want to learn how to use the materials room, I'm happy with the way P4 does it. You can't run both at once though. later jb
