Normally i would have to press my FN key when i want to use any of the F keys. But now its revered. I went to system prerences and then keyboard and clicked the 'use all F1,F2 etc' which enables using Fn for the F buttons. But it still wrong. Now i have to hit Fn to use the volume/itunes/light/display/expose and dashboard. This isnt the way it is suppose to be. can anyone help? Nevermind!! the keys are working now but in reverse order. I think its a glitch in software.
