Icons in System Preferences disabled
In System Preferences, MobileMe, Accounts, Parental Controls, and Startup Disk are disabled. More importantly, when I install new software, their configurations in the 'Other' section are also disabled.
When I try and access them via Spotlight, it says: You cannot open "<application>" preferences pane because it is not available to you at this time. You might need to connect a device to your computer to see this preferences pane."
When I hover over an icon, it shows: Your access to this preference has been restricted.
Is this an inherent restriction on the way in which my account was configured, or is there something I can do about this?
