Hi John (M)
For the moment the difficulty is that my scanner seems to think that because summer is here it can take a rest and stop working.
I shall give it a severe talking to in the next couple of days and get it back to work.
Hopefully I shall be in touch very shortly with a copy of the article!
Regards
Grumpy
PS Does anyone else find that their computer, printer etc just stops working for no apparent reason?
