A new version of screen, 4.2.1-2, is available in the Cygwin
distribution.  This is a new Cygwin-only test release.  

This release includes a patch that may fix the scrolling corruption bug
when screen is used in mintty in 64-bit Cygwin
(http://cygwin.com/ml/cygwin/2014-01/msg00223.html).  If you are
affected by that bug, please install the new release and report here
whether it fixes it for you.  Thanks to Shaddy Baddah for the patch

Note that since this is a test release, it won't show up in setup by
default.  To get it, in setup you'll need to select the "Exp" radio
button at top right.

screen is a full-screen window manager that multiplexes a physical
terminal between several processes, typically interactive shells. Each
virtual terminal provides the functions of the DEC VT100 terminal and,
in addition, several control functions from the ANSI X3.64 (ISO 6429)
and ISO 2022 standards (e.g., insert/delete line and support for
multiple character sets). There is a scrollback history buffer for each
virtual terminal and a copy-and-paste mechanism that allows the user to
move text regions between windows. When screen is called, it creates a
single window with a shell in it (or the specified command) and then
gets out of your way so that you can use the program as you normally
would. Then, at any time, you can create new (full-screen) windows with
other programs in them (including more shells), kill the current window,
view a list of the active windows, turn output logging on and off, copy
text between windows, view the scrollback history, switch between
windows, etc. All windows run their programs completely independent of
each other. Programs continue to run when their window is currently not
visible and even when the whole screen session is detached from the
user's terminal.
