I started my mac tonight when i got home from work, and one of the login items is Mail. I walked away from the computer to let it boot up and load everything, and came back to it and Mail was running. If I manually quit and relaunch Mail, it does ask me for my password.
Any ideas?
Followup: I noticed that "Autounlock at login" was checked so I am guessing that is the reason. However, why would anyone want that feature? If they want their data secured, a simple reboot of the machine would unlock all their data without any user interaction. Seems strange.
