You have  a valid point FCLitte.  I have a new machine (1 month old),  new drivers, new everything; everything clean, nothing else running, and Windows XP with every update that Microsoft ever came out with.  Bryce 6 crashes. Period.  It especially seems to crash on opening up IBL images - which is not good since I use IBL on just about everything now!  I put up with it the way you put up with a naughty child - because I love Bryce!
