------- Additional Comments From rami.autiomaki@pp1.inet.fi 2007-19-05 12:12 ------- I seemed to fix this by modifying /etc/xdg/menus/kde-applications.menu.
I added below <DefaultMergeDirs/> <MergeDir>applications-merged</MergeDir>
Now Wine menus work like they should. Is there similar line in other distros? Which is missing in Kubuntu.
