        Thanks for posting this here -- did you also send email to Tim
(tcasey <at> adobe <dot> com)?  He's the guy who really needs to see this, as HE'S
the guy who can fix the code!

        Just so you know how good it is now, I'll detail the bugs we found
in the first two games.  THIS IS NOT to belittle Tim or his helpers, but
just for purely historical interest :-)

        1) The initial setup White's rook where his bishop should be,
and vice versa.  I used this 'bug' to nail poor Tim.  He got his revenge
in the second game (fragment).

        2) You could drop two (or more, I'd guess) unpromoted pawns on
a file.

        3) We saw the 'ghost' pieces-in-hand bug that Chile mentions above,
but with a twist: when he dropped a piece in hand, it was replaced by a '?'
in his in-hand list!  He wouldn't admit what piece it represented :-).

        ANYWAY, this is really an outstanding piece of software; as I say,
I am more than appreciative of these guys' work.  Please extend them your
encouragement if you get the chance.
