I am not sure if this problem is within my computer systems or with Bryce 6.1 itself.

After working in Bryce, then you shut down...
Does Bryce leave stray bits from your files?
Is there a way to release unneccessary memory from Bryce when closing down?

I have used a few Default Presets that when rendered has not been the preset I chose, yet the correct 1 shows up in the Nano window at the time of render. This is very strange for me indeed as it has never happened before, and for the life of me cannot find what is causing this to happen.
For example one is the Grassy Peaks 2 and when render I see it has actually rendered as the Mossy preset.

Thank you for any help you can give me
God Bless
