Flak - ditto on things becoming randomly selected after moving an item.  In addition, I've noticed if I rotate an item & then go to another item, the item I just rotated snaps back into its pre-rotated place.  This is NOT limited to Poser items - it happens with native .vobs or any other type of object.

I have 8g(XP x64) so memory should NOT be an issue at this point.  That said in watching my task mgr while rendering - Vue is sucking down memory at a rate of 1000.  It drops with every second that passes in increments in the thousand area.
