Thanks very much for the information. I am now able to reproduce this issue.
This appears to be a change in the ssh client so that ForwardX11Timeout
applies, even if untrusted authentication cookie generation failed (See [1]).
It looks like this change first appeared in openssh 5.6, although I can't see
it mentioned in the announce email.
Note that if you had run ssh -v, you should have got a "Rejected X11
connection after ForwardX11Timeout expired" explaining what was happening :-)
I guess I'll add something in the Cygwin/X FAQ about this.

Thanks for the reply.
So far ssh -Y seems to be doing the trick.
Good.
I'd like to know a bit more about why this is happening, though, so if you
could share the OS and sshd version which is running on the machine you are
sshd-ing to, and the output when you connect using ssh -vvv -X, that would be
interesting.

I have installed cygwin on several windows XP 32bit machines. To do the
install I used the defaults and then installed all of X11 and
Networks. After a little while
about 20 minutes?
when opening a new windows, I get the
error:
The application 'gedit' lost its connection to the display localhost:11.0;
most likely the X server was shut down or you killed/destroyed
the application.
It doesn't matter what I do next, nothing simple makes the x-server come back
alive.
This
is happening on multiple machines. For some reasons I have other
machines that never have a problem. These machines may have older
installations.
Any advice is appreciated.
Use ssh -Y
