I guess that leaves me as the sole user of Poser 5 around here...;)

Nope, not the only one. I'm setting up 3 swappable drives with only XP & Poser for specific projects, as follows:

XP & Poser 6
XP & Poser 5
XP & Poser 4

P5 runs faster than Poser 6 on the same machine, and P4 is blazing fast.

I still have Poser 1 and 2 on the Mac, but can't seem to find my Poser 3 disc anywhere.
