I am more than delighted with Vue Infinite!  I've been using Vue since version 4; wasn't thrilled with 5 but do love Infinite.

Your crashing may be due to your windows setting - in your control panel, under System - click on Advanced, then on Performance - Settings,  click on Advanced under Visual Performance - your Virtual Memory could be the problem.  Mine is set at 3536 MB and does not crash.

I import pz3s, leave Poser 6 open and with the latest Vue update, if I need to go back into Poser to adjust something, it updates in Vue as well - a great time saving feature!

Hope you get your problems solved because it's a great program!
