Bug with using Meta-X send

[BATALI@MIT-OZ]

I send a message as follows:
(From EMACS):
M-X SEND
<type message>
C-Z C-Z

The message is successfully sent, but then I get a beep and the error
message:

QNS   Q-register not string or buffer?

Which goes away with control-L.

The next time I do M-X SEND, I get the same error message right after
EMACS prints out:
To:

Slightly later, another error message pops up saying something about
macrofying a number.  All these go away with control-L, but are still
annoying.  Also: after sending a message I would like to end up in the
buffer from whence I came.
