Hm, I think the trouble may be some funkiness in my object. I tried 180 MB and it still crashed. I modeled it in Amapi and exported it in Lightwave format, since Amapi doesn't do obj format. I tried the same operation using a simple ball prop and it didn't crash. And, once I put my figure together and took it to the Setup Room, "Create Perspective UVs" didn't crash Poser. (It didn't seem to have any visible effect -- does it just mark that group as being able to accept a texture, which can then be assigned separately in the Materials dialog?) Well, I'll use UV Mapper anyway, and chalk this up to a case of "Doc, it hurts when I do this!" -- "Well, don't do that!" By the way, as far as memory goes, I ran a utility that kept tabs on Poser's memory usage. It would seem that in the course of performing operations (posing, rendering, etc.) the memory required fluctuates by 1 MB or less. Apparently, giving Poser more memory lets you load more (or more complicated) figures.
