When I said imported I simply meant loaded, as it is not the same version of poser it was created in I refered to it as importing(old habit).  It's not a universal problem, as I do have other scenes with props that work just fine when I bring them into poser 7.  It seems I have had nothing but bad luck with poser from version 4 onward.  I always get strange behavior of some sort...with poser 4 it was the rendering engine causing bizarre artifacts all the time.
