I have a macbook fairly recent model, and I decided to do a fresh install of Leopard (10.5) but now all my top keys (F1-F12) are all out of order, I know i can assign secondary functions to them, but their main functions don't work properly, for example my mute, lower volume and raise volume keys are assigned to widgets, and expose. I tried searching this but turned up with no luck any help would be appreciated.
