in Writer open the Navigator window (F5) click on the "Play" button (second from left in top row) a child dialog pops up directly _behind_ the Navigator which is sort of a usability issue. this happens when running on gnome-shell with vclplugs gtk, gen and kde4 but does not happen on Windows. not a regression, happens since OOo 3.0.1
