Did you realise you were replying to a thread that has been dormant for seven years Tim?
I came across the thread last night and something odd in one of the pictures made me curious, I assumed the original problem has been solved long ago and whilst I thought of copy/pasting the picture into a new thread it would probably still have needed a link to this old thread to put in context.
Any idea why part of the picture is mirror imaged?
