I haven't gotten the message message thus far with the new Emacs Windows
zip file released yesterday (emacs-20111114-r106380-bin-i386.zip) by
Christoph Scholtes with newer window.el/window.c code.

I'll keep trying for a litle while longer to see if I can reproduce
it.

It sets the mark, (mark-whole-buffer), and (kill-ring-save) of the
*Message* buffer so that I could paste it in the new Emacs instance
to send my bug report.

Two.
