P6 is by far the best Poser yet, however, I am have a similar issue as well. I can switch rooms, change lighting, render, everything. But, when I attempt to save or export a render...Crashes to the desktop everytime. I do not use Norton or ZoneAlarm (use McAfee), so that eliminates that, and I have tried all the setting changes above with no luck. I can, however, copy image and paste into Photoshop, so I have a workaround until I can discover the issue.
