Jimmy, I saw the thread on the cygwin list.  I didn't answer there because I
didn't have anything to add.  In fact, you did get a response there from Matt
Wozniski, who I thought covered it as well as I could:

Maybe someone knows a solution to this, but I don't.  Although I maintain screen
for Cygwin, I know almost nothing of the details of how terminals work.  I could
imagine some kind of a DOS-to-Unix terminal wrapper program, but I've never seen
one and have no idea how it would work.

Please note that http://cygwin.com/problems.html asks you not to send problem
reports to maintainers' personal email addresses.  Such reports should go to the
Cygwin list, so that everyone can contribute to and benefit from the discussion.
If you want to call someone's attention to a thread, you can append e.g. "[ping
Andrew Schulman]" to the subject.  But at least in my case, it's not necessary:
I have my news client set to automatically flag anything that has "screen" in
the subject.

Sorry I couldn't help.  Good luck,
Andrew.
