After daily forum reading for the past year about the PC version of P5, there's no way I'm subjecting my poor brain to that learning curve! Unless DAZ Studio turns out to be less than we're all hoping for, I will never have a great need for P5 (and my fingers are crossed for DAZ). Once I installed OSX Jaguar, P4 began to work like a dream :) Nearly all the crashes and other horrors I'd endured just disappeared...and I'm running it under Classic on an iMac.
