Greetings, Takashi Yano!

> This also causes gnu screen to freeze.

GNU screen freeze without much of an effort under Cygwin.
Try detaching from running screen and then running screen -ls.

> To reproduce this:
> (1) Start screen in mintty window.
> (2) Detatch from the screen (Ctrl-A d).
> (3) Login via ssh.
> (4) Attach screen by 'screen -r' in ssh session.
> (5) Detach from the screen (Ctrl-A d).
> (6) screen freezes and is not terminated normally.

> This does not occur if the user does not belong to
> Administrators group.

> I guess this is a problem of setuid codes.
