Never had poser 1 & 2. Still have Poser 3. (A Mac/PC Hybrid CD, no less) I just purchased 5 for OSX on my mac. My 10 year old saw me working with it to create some scenes for her FFRP campaign and asked if I could put it on hers. Wasn't about to shell out the money for Poser 5 for her windows PC, so I put Poser 3 on her computer (Windows 2000) it's running great. Also had to bring it in to work, since our boss wanted a couple of things done. Vicki and Mike, btw work in Poser 3... at least on the PC side they do. Now... if I could just figure out how to get poser's blankety-blank-blank-blank hair room to work so I can add hair to this one figure!!!
