I havent had any problem opening older scenes and since it turns out you were "importing" hopefull we can lay to rest the "Poser7 can't open old scenes" meme that is even now approaching mythical status.

I can see it now, 2 years from now someone is going to say "Yeah, when Poser7 was released it couldn't even open my old scenes without killignmy dog!". I'll just shake my head and not even bother.
