Mplayer loses focus on view switch
if user switches views while (sticky) mplayer is active, mplayer will lose focus.
2 ways to see this:
a) start mplayer, make it fullscreen, switch view, try to get mplayer into window mode again. (will not work until you switch back to the view where you started mplayer.
b) start some app on workspace X. start mplayer on another view and switch to the view X again. mplayer will slip behind the started app. you dont even have to switch views. E.g.: Start thunar, start mplayer, open thunar preferences. mplayer will slip behind thunar.
