Uh oh...I just ran the Software Updater, and I see that there's an update for Network Connections.
Leenie, are you still having issues? Did you install that update for Network Connections AND THEN the problem started...or...did the update for Network Connections fix your issue?
I'm scared to let it install the update!
I think I'll install wicd first, then try the update to see what happens...at least I'll have wicd as a fall back if needed.
