I had problems bringing in Poser scenes or characters into Vue 5.  It crashed every time.  I'm holding off buying Vue 6 because there are many issues not addressed in their "improvements."

I never had problems with Vue 4.  Vue 5, for me, was a disapointment and a mistake.  The upgrade path is also too expensive especially for a program that had beta problems.  As far as I'm concerned--it's still a beta program.
