Gosh, I didn't expect anybody to really have a spare one, and now I've got two offers! :-) I will borrow Art's first & see if that fixes the problem; & if it does, since that's only a loan, I may take you up on your offer -- thank you! (How much would you want for it btw? They seem to go for 30-60 quid on eBay, new-from-Apple price is about 65 quid IIRC.)
