Oh lawdy lawdy, Maisie Doats and Davemano, we sure seem to have stirred up a can of worms!! Very rarely can I help others because usually on the ones that I know, then others seem to answer before I get a chance. Thank you for that clue with 'old nick', I will have a search around. I had noticed that some of the people who are usually very vocal, have now gone very quiet for some reason?!?
