ronstuff,
I forget who it was but a couple of months ago or so someone was trying to rescale in an animation and ran into this or a similar problem.
Apparently, at least in Poser 4, there was no simple solution. There is some utility from DAZ(?) I think that was supposed to address this.(not sure - I think it's called Scaler(?)) If the member that was working on this doesn't chime in, you might try to find that thread in the archives. Try under scale or scaling. Sorry not to be of more help.
