You haven't specified exactly *how* you invoke the applications on
Linux,
but I suspect they are X applications and you invoke them via the X
forwarding feature of ssh.  This makes your question off-topic for the
main list, and on-topic for the cygwin-xfree list (which the Reply-To of
this message points to).  If you aren't using X, please follow-up to the
main list with more details.

As for your problem, in the absense of more information, it looks like
you're seeing weird Num-Lock-related behavior, which is a known problem
with Cygwin/X.  Try using the digits above the alphabetical keys instead
of the keypad.  I also seem to recall some recipes for making Num-Lock
work properly -- searching the cygwin-xfree archives may help.

Scott,

Another thing to check is whether you're hitting the limitations of
untrusted X forwarding (see the Cygwin/X FAQ entry on ssh).  Also, does
this problem occur only in those applications, or in any X application
(e.g., an xterm)?  If the latter, you may have keyboard mapping issues
--
the output from pressing those keys in xev might help.  If the former,
try
eliminating ssh as the culprit (e.g., temporarily opening up the local X
server with "xhost +" and setting the DISPLAY on the remote machine to
connect directly to the local server).

It would also help to know what you use to start your local X (there is
no
such thing as startx.sh -- there's "startxwin.sh", "startxwin.bat", or
"startx").  Do you have a ~/.Xserverrc?  What window manager are you
using?
HTH,

Igor,

I am using the -Y option so I do not think it is a limitation of
untrusted forwarding. The problem does not occur in xterm or konsole
applications. It only seems to occur in two design applications I have
tried: Cadence IC works and Slam edit.  
You are correct there is no startx.sh.  I am using startxwin.sh here. I
am using the following command lines:
XWin -multiwindow -clipboard -silent-dup-error -multimonitors
-emulate3buttons 100 &

xterm -sl 1000 -sb -rightbar -ms red -fg yellow -bg black -e
/usr/bin/bash -l &

In this case, I am using the integrated windows based windows manager. I
do not have a ~/.Xserverrc. I have considered trying the twm option. I
will try to rule out ssh. Thanks for your help.
