Tho i tried adding that value by myself i think i might have succeded with your idea Yzöwl, the Documents folder isnt there anymore and that line you posted should it remove the Documents folder or just the refreshing files inside that submenu?
See if you can help me with my problem, in my attached pic i got an menu called Dokument, how would i do to remove it or just stop it from refreshing what files ive used? http://i3.photobucket.com/albums/y73/Frysdisken/temp.jpg
