I'd love to argue this point till we all cry. But I won't. If your having trouble installing stuffit for the PC, it's not a MAC problem. I have installed many versions of stuffit expander on many different PCs (from an old 486 to a 350 mhz pentieum) and have never had a problem. Just try a clean install, or maybe even try downloading it again and then re-installing. I have also known the wonderful people here to rally together and send someone a converted (zip) when all hope was lost. James (Yes a MAC person) It's not the computer, it's what you get out of it that matters. So get over the PC war and back to the commonality that is the Poser Forum.
