Update:

I set the min shade rate to 1 and was able to render the entire picture at the finished quality level in Firefly AND then I was able to return to the pose window without a crash! Yahoo!
Thanks Bagginsbill!
But, then I added to and modified the scene and tried a re-render at the same render settings but a larger image size and the render ended real quick and I had nothing for a render but a black screen. : ( Then when I tried to go back to the pose window I go the crash.
But at least Bagginsbill has helped me a great deal. I have been trying to render this image for a long time and have not gotten this far.
So, maybe now that Poser has had it's more recent tantrum and been closed I can re-open and successfully render a larger version.
