Well yeah, come to think of it, where was my head the other day.  I could not
explain one thing in easy terms.

Of course, Wine doesn't do it that way, it currently relays through the
standard X11 methods, this is the problem.  X11 behaves differently than
windows.  We just need to find a way to get around this when programs don't
consider that undocumented Windows behavior may change.
