Hi again, I have just discovered Winslo's posting, and realise mine was superfluous, sorry. In my defence, I can only blame our mail server, which is doing some *very* weird things just now. (Don't you just HATE computers)? Thanks to Barry S. and Winslo, for the nice things you said about my item on the trem. harp. I came over all bashful like folks :-) Gordon
