Eh, now wait a minute again... - does not that mean that if
foreground_window is not 0 then the "|| foreground_thread =
GetCurrentThread ()" will be executed? (As I said...)

And I do not think that is supposed to happen. Or do I get something wrong here?

Why is it so easy to get this simple thing wrong? (I think I know the
answer, but it hurts my feeling as a human being. We are supposed to
be the most logical animal.)
