Has the unit actually changed, or just how they define it? If you import a P4 box that is 1 Poser unit square is a different size than a P6 box that size? If not it is a tempest in a tea cup, everything will stay the same size, some will still think 1 Poser unit = 96", some 100", some (now) 103.2". How tall do you want Vickie to be? ;-) Incidently, 1 Poser unit = 1 Max unit, anyway.
