GNU Emacs 21.2 (i686-pc-cygwin, X toolkit)

[Charles Notley]

My platform:
I'm running CYGWIN_NT-5.1 1.3.15(0.65/3/2) on top of XP with all patches 
current as of today.  I downloaded the cygwin environment from cygnus 
today and also have PRC-tools installed.  I installed everything from 
binaries using the setup utility http://cygwin.com/setup.exe.

The problem:
When i try to exit Emacs using the keyboard command, C-x C-c, it doesn't 
exit.  The word "Quit" flashes in the lower left corner of the window 
and my pc emits a dull beep from the internal speaker.  I am able to 
successfully use other keyboard commands such as the saving the buffer 
to a file.  I am able to exit normally via the menu keys.
