Excellent stuff... Have turned it to "On" and it is now doing what I wanted! Thought you had said to turn it off before. My user manual only has 82 pages so couldn't find the section you were refering to. I now think that I need to be looking at the pdf manual on the CD rather than the hard copy?
I was sure I had tried this with it set to "on" before, but obviously not. Many thanks for your help!
