It started a few days ago after a Windows Vista update... whenever a secondary window (ie: when I conform a figure to another, selecting lighting color, the render progress box, etc...) opens, it will not close, even after several minutes, and ultimately causes the program to loop-crash.

I have searched the SmithMicro website and found no reference to this issue.

Anyone else have this problem?  Found a solution?

It's making it very difficult to use Poser without being able to render :)
