Hi,

I am currently at a customer where the security policy does not allow me
to simultaneously connect my laptop to the Internet and the local LAN.
However, there is a Windows Terminal server with a web browser that I
can use in case I need to browse the Internet while connected to the
LAN.

This server is configured so that if the session has been idle for more
than a certain amount of time, the connection is dropped, server-side.

In itself, that's not a problem.

However, it becomes a problem because this usually happens when krdc is
on a different virtual desktop (otherwise I would've seen the warning
that the server sends out two minutes prior to disconnecting), and upon
disconnect krdc unmaps the full-screen window, and remaps a
non-fullscreen but maximized window right after that, unconditionally.
This remap causes it to be shown on the then-active virtual desktop,
interrupting any work that I may be doing at that time.

The fix to this is easy: rather than unmapping the normal window when
going full-screen, it should be brought to the background. This way,
when the full-screen window is removed, the maximized window does not
need to be created, and will remain on the other virtual desktop.
