XFCE missing menu entry

After installing some programs under wine, Xfce made the programs available under the menu “other”, but now that menu has disappeared.
How can I get it back?

The menu editor is gone in xfce 4.6 but maybe you can follow the xfce wiki

and the topic about the menu editor in the xfce forum
How can I edit the new menu specification in XFCE 4.6 Beta?

I restarted the Xfce session and it was back on the menu.
