Comment 9 for bug 930563

I have this problem since i updated from ubuntu 11.04 to 12.04.
I use ubuntu 12.04 on my incar-pc with wireless connection set to automatic connection. As i drive around my pc is reconnecting on several networks ( home, work, clients, and other ( non-secured) available networks ).
When i have no wireless network in range i want to get my mobile 3G network activated but the nm applet does not respond.

At start up the nm responds but after losing connection ( out of range as i drive away) and reconnecting on another wireless network the nm menu can open but does not respond anymore. Every mouse click just closes the nm menu.
Restart ubuntu or restart nm service resolves the problem.
