Thanks for all the advice. I'm still nervous about trying to upgrade from the free P3 because if it turns out I can't do it, I doubt I can return the software! Also, don't I need P4 before Pro is any use? I thought Pro was just an add-on thing and I don't think I need to go that far just yet (also, P4 plus Pro costs 3x P5, from my research). I'm in Australia and just finding someone who sells Poser is proving a challenge. Will read the other threads too - thanks.
