I started this in P6 which took at least 10 min. to load, and FF wouldn't render it.  It just froze like a Deer in the headlights.  No wonder too, there are 50 figures in it and I wanted to add more.  It took just as long in P7 to load but rendered in 4min.  Superb--I've been waiting to finish this, it looks like P7 can handle it now.  Things are looking up!

Under the hood: 3.6g HT Intel chip, 3G ram, SCSI HD & ATI 9800  VidCard.
