Hmmm. That sounds like a Poser limitation, nahie. Remember that Vue calls to Poser for the animation functions, and Poser is still a 32 bit app with the first 2 gig address limit. That 1.5 gig is just about the right number to be running out of allocated memory for a 32 bit app, as the OS would be eating the first half gig. Hopefully everyone who answered the EF survey marked 'the whole application' on the question of how much of Poser should go 64 bit.
