Hi all I have recently purchased a new aluminium wireless keyboard - It's connected and working, trouble is though the new F key functions are not working. e.g. when I press volume up (F12) on the wireless keyboard the dashboard opens! Also the dashboard (F4) expose (F3) and brightness (F1 & F2) butons don't work on the wireless keyboard. On top of that the standard volume and brightness etc F buttons on my Macbooks own keyboard don't work at all now! Help!!!
