I recently wanted to switch from the default OS X behavior where function keys trigger things like brightness control and volume and expose, etc. to having them register as literal function keys. I went into the keyboard prefs pane and found...no reference to function keys.
It should look like this:

Also attached is the display of FunctionFlip, which is a 3rd party pref pane that lets you customize the function keys beyond what Apple offers in OS X. FF sees no function keys on this keyboard, either.

I realize the Leopold FC660C has "virtual" function keys, but shouldn't they register to the OS? As it is now, I cannot use any software on this Mac (running OS X Mountain Lion) that needs direct function key input.
Has anyone found a solution to this issue? Thanks.
