I have also had major problems so far. I currently use Bryce, Vue d Esprit, PS, PSP and many high end audio and video editing products which I have not had any problems with. In fact, I quite enjoy my experience with all of the above mentioned software. Enter Poser 5! Upon loading this much anticipated software, the program itself was very
frustrating. Unable to load figures and clothes simultaneously, crashes(lots of crashes) and very difficult to load new content(tedious and drawn out). All in all my initiation to the poser world has been one of extreeme frustration due to a very buggie program. Please, please, please, staff and management at Curious Labs read these posts and respond accordingly. I don't understand why this product was released before it was ready. To make matters worse, installing this program on my Athalon XP 2000 with 512 Megs of ram, has created problems for my entire system. It used to run flawlessly.
So it is with regret that, based on my personal experience with this product, I would also not recommend purchasing Poser 5 until the programmers are paid to come back and fix all the problems with their program. I feel I must join in here and honestly share my experience because I would hope others would do the same for me.

Good Luck
Happy Posing
