--- Comment #6 from superrobowizard@gmail.com --- I installed winbind (according to ubuntu software center I already have libgnutls). Not a problem anymore, it launched in windowed mode this time :) So at this point it's just a small hitch that needs working out. I down't know much at all about code, but maybe this could be fixed by refreshing the desktop environment or something when the window changes type?
