Sharing Preferences becoming unlocked without knowledge
I always keep my Sharing/Firewall preferences blocked. I have everything unchecked in the firewall, the firewall on, and I only share my iTunes port.
I have a Powerbook that requires a password to log on and is in my possesion %100 of the time. Yet lately I have checked my sharing preferences and although nothing is changed, the preferences are unlocked??? I lock them, unlock them with my password(to double check), and then lock them again. But if I check back again later, the preferences pane is unlocked???
Also, when I received my PBook back from AppleCare, there was a new login option of guest (other?) on the startup screen, but I cannot get rid of it in the accounts pane.
How can this be? I am worried about someone or something accessing my computer. (That I use for work, some of which confidential)
Any thoughts?
EDIT: Apparantly it happens after a restart.
