If I wanted to get rid of Poser Pro, and shift to Poser 8, would I just copy the runtime file from Poser Pro to Poser 8, or is that asking for trouble?  My Poser 8 works perfectly - far better than Poser 7 - faster and the renders are faster (running VISTA 64 with 8 gigs memory, latest updates).  seems like a waste to keep separate runtimes.
