Every time we change the setting on an iMac running 10.6.8 to not log out after X number of minutes the preference seems to reset to log out after 55 minutes. We don't want the computer to log out as we are running a looping movie and the computer sees this as no activity.
As soon as we change System Preference panes the log out after X minutes resets to being selected and set to 55 minutes. does any one know how to disable this feature/preference? or know what plist needs to be replaced (assuming that the plist is corrupted and will not hold changes)
