Ok, part of your problem might be the ctalyst control center. Almost EVERYONE (except ATI) says to NOT download the driver version with the ati center, and ONLY download the drivers themselves. I tried the control center once, found some slower game performance, and dumped it after 1 day. (It maybe be trying to apply settings that should NOT be used with poser 6.) You'll need to download ati's remover utility to remove all the junk they installed, including the driver, and then install JUST the latest drivers available from thier website. Once you reboot, set your desktop size, and options you normally use, and then attempt P6.. this might clear it up. Actually it might clear up a LOT of ATI user's graphic issues, but I thought everyone knew to NOT use the ati control bloat center.

Way too many people take way too many things way too seriously.
