If you have a powerful processor-- over 1.5G-- and lots of memory--1G is best I have 2Gs-- then Poser 5 can be a very enjoyable experience. I have tons of stuff and could not stand the library situation in Poser 4 and PP one more minute. I also had more freezing in 4 and pp from the bumps or jpgs that weren't there as well as the memory leak that affects Poser 4, Pro Pack and Poser 5. It's more noticeable in 5 because 5 is slower. I like the improved rendering in FireFly and I would never go back to the mess of libraries I fought through before. I don't make hair, I haven't tried the cloth room because it seems like a ton of work for one instance of dynamic cloth. With a smaller, pared down Poser 5 runtime, I rarely have freezes. When I have them, it is in rendering to a larger window, I ctrl-alt-del and reboot and go on. Mostly this happens with VIcki3 who is a lot of meg for Poser to handle. If we were all working with just the morphs that we were using in Vicki3, there would probably be less probs, but I'm lazy, I haven't saved out all my characters yet in slmmed down versions. Poser 5 on my hefty machine is not a major problem to run. I can do multiple person scenes as long as they are not Vicki 3. I don't do animations so the problems with collision aren't making me miserable. Honestly, I think you would be happier having Poser 5 if you also had Poser 4 or PP. But it is not the complete disaster they first issued, no where near. It is a slowish, but very versatile program. Emily
