Thank's for the link stewer, that's interesting and i'll now give that a go for future piece of mind but I'm dead sure I've done more complex renders than this in P5...OK it did take a LONG time but it never used to 'bum out' as readily as P6 does! But then I s'pose some might say that's a good feature? Hmm, maybe i should come at this whole P6 thing from a different direction! I do genuinly love some of the new features in P6, my personal favorite is the extended Library pallete which i have stretched right across my second monitor!! Thanks again stewer
