Re: "Repair" function

[Jason Mellein <mellein MIT EDU>]

When I right click the icon I see

"Pause Wireless Scanning"
"Stop All Wireless Devices"

The second option is grayed out. Is there a reason for that? I can't 
stop & restart if I can't select the menu item. :-)

Thanks again. When I switch buildings in 1/2 an hour I'll try clicking 
on the MIT connection in the drop down to see if that reconnects me.
