Thanks for the info Andrewbell.  I was wondering if the multithreading feature was really that good. I have vista and 4 Gigs. I have been reluctant to upgrade to Poser 7 or 8 only because I was concerned that many of the scenes and much of the content I have might not work. Have you had any problems using content or opening scenes that were made with earlier versions of Poser. If not I will get Poser 8 soon. Are there any problems  with Poser 8 ? Thanks
