This *sounds* like an old bug I ran into where the nm-applet (the 
graphical icon with the pull down menu) got out of sync with what the 
underlying system (NetworkManager itself) had for the wireless network 
list.

Can you run "nm-tool" in a terminal window, then run "iwlist scanning" 
as well (I think the latter needs to be run as root)?  That may 
provide a clue as to what is being misdetected.  The two should agree 
on the list of APs found, their encryption modes, etc.
