Lyndel, thank you so much. Firstly for moving this thread to the right forum (blush!) and secondly for the link which we had not found. Had a quick look over breakfast coffee, but it's one I need to read carefully and work through just as carefully, since our sole use of Windows is for the Pronto...

I'll let you know how we get on.

Thanks again  (virtual 'cheers' smilie here!)
