Alright, this is possibly the strangest bug I've ever encountered on my mac. Right now, in my System Preferences, the Accounts pane won't load. Every other pane, including custom ones, works fine. But if I click on the Accounts pane, it chills there saying "Loading Accounts ". If i click it again, it pulls up an empty pane. Also, under the Sharing pane, if I go to SMB sharing and click "configure accounts", nothing happens. I assumed it was permissions, but that didn't fix it. I did a full disk verification too, and that didn't help. The pref pane is there, I have read permission for everything, and the .nibs all open up in Interface Builder fine. Has anyone ever encountered this bug before, or have any suggestions as to how to fix it?
