I cannot see how MSEgui handles dockable (floating) forms. On Windows a 
form can react on mouse down in the NC area, while other window managers 
apparently(?) do not notify a form (window) accordingly. That's the 
*only* problem with platform independent drag-dock, and nobody (here) 
seems to have a solution for it :-(
