When dragging windows (workspace, output) around, it
is very easy to lead to the situation when they
disappear from the screen, or when only a bottom
corner of a window is visible, so that there is no way
to resize a window and bring it to where it ought to
be. Even reinstalling WinCvs doesn't help because it
will remember its screwed-up settings somewhere.
At the very least, there should be an option
to "restore layout" or something of this sort, to
bring all windows back in place.
Ideally, a window would NEVER completely disappear
from the screen as a result of moving it around unless
it is explicitly turned off in the menu. It should
also always be possible to resize a window.
