Hi, Yes I've unchecked the Automatically illuminate keyboard in low light box in keyboard in system preferences. I'm on Lion now and just discovered how to make my home library folder visible again, and I was in my preference folder trying to find something like com.apple.keyboard.plst. Sometimes when you put the plst file in the trash and restart your Mac that usually fixes the problem because the Mac makes the whole new plst file. However I didn't see com.apple.keyboard.plst is it there or under a new name??? Thank you for helping me.
