Hi
I sent the message below earlier, but it never showed up in my mailbox (or
in the archive, but then a lot of messages don't seem to be in the archive).
Anyway, rather than send another 5K attachment, I've added the source file
to my web page, http://www.best.com/~petec (though you'll immediately be
asked to go somewhere else...)
If anyone *did* receive the earlier message, you'll probably want to make
the class public (I'd been testing it as a local class and forgot to add
'public' before posting it).
Cheers,
Pete
