It is Windows specific, and is fixed in HEAD. The fix
that is in HEAD caused other problems in the RC branch
so it was taken out before 21.2 was released.

Is this really Windows-specific? If so, would someone who works on
Windows please look at it?

That looks a lot like another report for Emacs on MS-Windows, for
which Jason said it was Windows-specific.

Cc: emacs-devel
I've tried it on GNU Emacs 21.2.1 (i386-msvc-nt5.0.2195) of 2002-03-21
on TAK_4100 which is almost identical to the reported build, and could
not reproduce the described phenomenon by using "Task Manager"
(configure to stay on top). It might be something to do with old
version of msvcrt.dll or some sort of system issues rather than Emacs
issues.
