Can't re-create your problem on my system.  My systems stays pretty much on 84% resources avaialable with simple scenes.  Drops down to about 54% with the latest picture I'm working on, but this one has a ton of Dystopia buildings and Poser imports plus lots and lots of lights.  Rock stable so far.  All of the bugs that were bugging me before seem to be fixed.  

Anyone notice all the new textures and atmospheres we got?  I'm a happy camper.  The only thing I'm doing now is getting everything moved over from Vue 5 so I can un-install it.  

Now, at work I installed Vue 6 without having Vue 5 installed on that system.  It did give me some hassles with checking for a valid Vue 5 liciense.  I just gave up and said no.  MAYBE, that is causing a problem?  Did not really have any time to play with it a work - I only install it there to test it on a "crappy" system.  I don't really use it for work (more like play around during lunch).  Anyway, at home I did not run into that problem and Vue installed all happy.  If you continue to have problems, it may be worth the time to install Vue 5 Infinite, un-install Vue 6, then re-install Vue 6...
