I know. Look at the discussions I had with Alexandre trying to fix this,
http://www.winehq.com/hypermail/wine-devel/2002/01/0416.html (my patch is
at http://www.winehq.com/hypermail/wine-patches/2002/01/0135.html)

It also happens in Gnome if you enable the gnome panel's "keep-on-top"
option. It may be possible to add an additional window manager hint for
WS_EX_TOPMOST windows that will make that window stay on top of those
panels.

Yes, Alexandre mentions popup menus and tooltips. Perhaps a chart could be
made, so that it is possible to work out what conditions should be used to
decide whether to make a window managed...
