Keyboard settings not saving
After a recent update to 10.8 I have been unable to set either the "Adjust keyboard brightness in low light" or "Turn off when computer is not used for:" options under keyboard settings. The check box and sliders are usable however after closing System Preferences any changes I have made dissapear. Any ideas?
