Each OS is on its on HD. I forgot to mention that Mac OS runs on a 120gb WD Passport drive. It took about a week of tinkering to get it to run on that.

For me, Poser 7 ran beautifully right out of the box. Poser 6 was the opposite. It took 3 service releases before the memory leak was even addressed, and even then it wasn't 100% fixed. I think e-frontier needs to deprive its code monkey's of bananas for a month thanks to this :)
