I'm really starting to get frustrated with my copy of Bryce.  V.5 was rock solid for me.  7.1 seems to crash when I do spray render, instances or even just holding down the shift key to turn terrains at 45 degree turns.

Is there some sort of patch out there for this or is it a 'feature' of the software to be so unstable?  It's really frustrating to see such potential dashed by crashing constantly.
