Clearing the echo area

[Robert Marshall <spam@chezmarshall.freeserve.co.uk>]

I guess this is an issue with emacs rather than vm (which I use for
email).  Whilst vm was starting up I resized the frame and obviously
did something wrong as I then typed g (for getting new email) and my
pop3 mailbox password, nothing happened, I typed n a few times in an
attempt to move about the mailbox without any effect, eventually I go
back to the main emacs frame and I see in the echo area

'nnnnnn g<pop password>'

Looking in the *Messages* buffer I saw
w32-handle-scroll-bar-event: End of buffer

Tried a few C-g's to get tid of my password display, tried find-file,
that seems to clear it, but then when I change buffer or scroll, it =
the display of nnnnnn g<pop password> keeps coming back(!)

apropos echo gives me nothing relevant (IMHO), what am I missing?
