The above is the only part of your message that belongs on the main Cygwin
list (see <http://cygwin.com/lists.html#available-lists>).  To be able to
use Ctrl-C (and Ctrl-Space, and a couple of other commands) correctly in a
cmd window, add "tty" to $CYGWIN before launching the shell (see
<http://cygwin.com/cygwin-ug-net/using-cygwinenv.html>).

The rest of this message belongs on the cygwin-xfree list.  I'm
redirecting this reply there -- please post X-related follow-ups to that
list only.

Try the "-fn" option, e.g., "xterm -fn 10x20".

A WAG: you mentioned ssh in the subject, but it's never come up.  Do you
have nedit problems when connecting via ssh?  Did you read the FAQ:
<http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-ssh-no-x11forwarding>?
If that's not it, perhaps someone else can answer.

Try giving the "-multiplemonitors" option to XWin.
