I found Poser 6 lying on the sidewalk where the delivery guy threw it over the gate (nice). The disk wasn't broken. My first upgrade in four years, from Pro Pack to Poser 6. I was sooo excited Not to have to launch OS 9 in order to startup Poser, and then it hung there on the title page, taunting me. Maybe it had something to do with the reg pop-up. Restarted, it came up and I love it, so far. It seems to run so much faster on OS X only. I'm running it on a G5 dual 2Ghz with 1.5 gigRam. And now the scroll on the mouse functions!! I'm hoping to get back to my comic strip (as are some others) : 0 All this to say, upgrading from Pro Pack has seemed worth it. I will let you know, in the future, how stable it is on the Mac. cheers!
