First of all the specs: Windows Vista Ultimate 32 bit, Vue 8 Complete, Poser 7, NVIDIA 8800 GT graphics card, 4 G of ram. I am running Vue Open GL under Hardware Assisted. I have updated my driver.

My normal workflow is to frequently use the preview render option to determine if I am going in the direction I choose. Such as frequent previews of ecosystems or even people to see that the materials are correct. Vue 8 does preview render correctly but seems to have issues with switching back to the normal state. There are very long hang times and all 4 views go blank. Also, without clicking on anything, the preview render goes away on it's own. Usually when I'm in the middle of looking at the results.

Anyone have a clue what is causing this?
