I'm really encouraged by the original post in this thread. I just recently started in with P5, and have found it to be a total nightmare - including getting some errors with SR-1 that I didn't get without it. I'm finding it slow, getting crashes, the renders inferior to P4 even with the 'quality' settings on, etc. And that's on a machine running at 1.6Mhz, 1 gig memory, and XP. In short, I'm still using P4 because I'm finding P5 totally unusable. But while I'm a bit miffed at CL for releasing the software in such a sorry state, I retain my faith in the company. I'm hoping for the final SR-2, and maybe an SR-3. As soon as they produce a P5 that works (and I'm sure they will) I'll start singing their praises again. Morphy
