I still get that often. You can up your virtial memory, but do NOT go over 3000, things go screwy then. I'm running windows 2000 pro with Poser Pro. 1gig of memory. This problem is never consistant. I can render a pic 2000 x 2000 one day, try again the next SAME pic, nothing changed and it won't do it. Visa versa, somedays I can't, come back later and it will. Poser HP has a bit on it, but their instructions for changing the memory thing is screwy. Made no sense to me.
