I've seen many posts hereabouts that say Poser won't use more than 2 gig of memory period, virtual or otherwise. Actually some have said that it's a Windows limitation. I don't know one way or the other. Anyway, it's been 35 mins, the memory usage is still the same, CPU still maxed, machine not stalled, just Poser. FYI, the pagefile usage is 1.3 gig total by all processes running, so it's not even reaching that limit.
