Hi there. I'm new here with Poser 2012 64bit and having a blast with it but encountering some issues I would hope some could help me with.

After I've done my setup in the preview screen and then render the scene, it takes a while before I can access the preview screen to rework the scene I'd been working on. Though the render times are really fast, its the wait time after that to get back to preview mode that is slowing things down.. The wait time to get back to preview mode takes longer than the render time.. even if I wait a few minutes to save the image etc, going back to the preview screen takes a while, almost as if the software is hanging, but it comes back and I'm able to compose the scene in the preview screen at normal speeds..

My system is a Vista 64, I7 processor, 16G memory and 1TB HDD with a 6750 2G video card. All drivers are updated, as is the software.

I've cleared the 'undo cache' found in preferences and even restarted the program but the longer I use the program, the longer the wait time gets until I have to reboot the system and start new again.. 

Has anyone encountered this before and know how to resolve the issue?

Thanks in advance for any assistance..

Cheers!
