So I realise that it might be helpful if I clarify myself, the desktop shortcut file for Eclipse would contain something like this:
[Desktop Entry] Version=4.3.0 Name=Eclipse Comment=IDE for all seasons #Exec=/home/USERNAME/Dokument/eclipse/eclipse Exec=env UBUNTU_MENUPROXY=0 /home/USERNAME/Dokument/eclipse/eclipse Icon=/home/USERNAME/Dokument/eclipse/icon.xpm Terminal=false Type=Application Categories=Utility;Application
The row Exec=env UBUNTU_MENUPROXY=0 /home/USERNAME/Dokument/eclipse/eclipse, part referenced in the post I pointed to, is the one that makes menus visible, et voila! :)
In my case this file (eclipse.desktop) resides in /usr/share/applications/
Hope this helps.
