Ok, i would understand "maybe" some feature not to be supported in a keyboard that it's more than 8 years old, but it is frustrating to see that the above mentioned buttons of the keyboard just do not appear not even at the preference panel of LCC and their functionality has been crippled since, instead of doing what they are supposed to do, they both just push and restart the play of a song in itunes, exactly as the play/push button above them...
This occurs also in tiger as well as in Leopard.
