Apple Wireless Keyboard Function Buttons Don't Work

Hey guys, I have an Apple Wireless Keyboards and have noticed a problem with it. So the wireless keyboard has the EXACT same layout as my MacBook keyboard, so I would assume it should function the same. You know how along the top there are lots of function buttons? Well none of those work like they should. Clicking any of the buttons from esc (very left) to the play/pause button doesn't do anything. From there, the forward button (>>) does what F3 should, the volume off button does something I'm not quite sure what it is the volume down button pushes everything off to the side of the screen (not sure what it's called ) and volume up opens my dashboard.

So is this something completely wrong with my keyboard, or is it something weird that they all do that I don't know of? Thanks for the help

 

I just checked my software updates, and there was one for the aluminium keyboards. I don't know how I missed it, but it's solved all the problems. Thanks for the help anyway
