That would be brilliant Henry, and thanks also to Alan for the explanation about the hamburger.
Henry, I have TeamViewer (sic), but I'm not very familiar with it, so you may have to explain to me what to do. Could you phone me on 01372-468777 to arrange the time? If today isn't convenient, any day (soonish) will do, since there aren't many appointments in my diary for some reason.
(This may arrive twice. This time I sent it via the forum, but before that I replied to the e-mail, and I don't know if that works.)
