You know when you go into System Preferences and in Network or Security you can go set your stuff and then click the lock icon in the lower left. It "clicks" and now shows a locked lock. Ok, so I go back in after exiting and the lock is still locked as I wanted. Good. But later, like the next day or later after I've reset the computer for some reason (like a recent Apple software update), my locks are all unlocked! WTF?
