Well the simple answer is that NM executes wpa_supplicant itself and 
supplies appropriate arguments so you either have the NM daemons running 
(which allows the applet to appear and be used) or you stop them and 
start the wpa_supplicant daemon.

Having all three daemons running together is a recipe for problems, if 
not actually disaster.
