I am using Lubuntu 11.04 (which I installed from Ubuntu). I tried editing menu.xml in ~/.config/openbox, and also tried using ObMenu. But Lubuntu continues to load the default settings with right click. Rebooting or re-logging in does not help. I see that the menu.xml file has changed and there are new entries.
I would like to create a rich right-click menu (also, if possible, application-specific right-click menu).
