Hello, I don't understand why System Prefs asks me for my password to relock after I already entered it seconds earlier to unlock. Network prefs is where this happens, and it occurs about half the time. I'm hesitant to blindly enter my password whenever I'm prompted when it seems to be out of place like this. I'll enter my password to unlock so that I can make a change. Then when I relock it asks me again. If I do not enter the password, and instead close the password box, the entire Network Prefs window contents disappears leaving a blank box. System bug, or malware/intrusion? Thanks.
