Do you have the preferences set for  Poser running in "Tablet Mode"?  If so, try turning that off and see if it fixes.  Recently there was another problem with Poser crashing and the solution was to turn off the tablet mode because their new tablet seemed to cause problems with Poser.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
