P5 is great, isn't it? (A CHALLENGE, but still great). One way to tell... In the original P5 Judy wouldn't morph (for me), and Don sort of half-morphed. Open Don, & check to see if his Left Collar & Shoulder have the same dials as the Right side. Also, you could click Help> About Poser and then look at the version # below your name. (Mine says v5.0.1.241).
