network mgr applet - cannot disable wireless

[Genes MailLists]

   Often when I do backups on laptop, I'll plug in wired ethernet - NM
happily switches the connection from wireless to wired -

 however it always leaves the wireless on as well
     + correct if its a different subnet than wired
     + arguably wrong if its the same subnet - probably a bug ? - or at
least it should offer to shutoff wireless when the 2 subnets are the same.

      Since the route via wireless is active, the backup could/does use
wireless instead of wired. So I usually right click the nm applet and
disable wireless.

      Today - that option along with the disable netowrking option are
grayed out and I can not uncheck the 'emable wireless/networking radio
buttons.


   	This is f13 - fully updated (+ some testing and 2.6.32.6-47 kernel
from koji). NetworkManager is 8.1.4.git20100817.


       Anyway know what causes this or suggestions on how to deal with it ?

        Thanks ..
