Hey all -- I seem to have broken the Date/Time pref pane. I can start up, log in (clock is accurate), run programs, start System Preferences, and make all kinds of changes. But if I use the "Open Date & Time..." menu item under the menubar clock, System Preferences launches (the app. name appears at the top left), but no window opens. Also, if I launch Sys. Prefs. from the Apple menu and then try to, lets say, change my time zone, Date & Time asks me to authenticate (appropriate) -- and then after I type my admin user and password, it hangs (beachball). If I force quit Sys. Prefs. and re-start it, I can open the Date & Time pane, but the little lock icon is missing and the pane still says "Authenticating...". (In other pref panes, it is shown unlocked.) Then if I click anywhere in the pane, it hangs. If I force quit and restart Sys. Prefs. again, it will hang if I even click on Date & Time. I've tried restarting, permission repairing, PRAM zapping, "fsck -fy"-ing, and com.apple.systempreferences.plist trashing -- all to no avail. Any help would be greatly apprciated!
