Hi, I intend to buy poser since I need to create many figures that would participate as the "Dark army" that the villain in my movie summons. first of all: 1. should I buy poser 4 or 5? 2. can poser 4 work on windows XP? 3. what figures do I have to get so I can enjoy a wide range of characters (with an emphasis on fantasy creatures of all sorts)? Thanks in advance, Eran - StoryO's Productions.
