Installed a new bluetooth keyboard today. Now my volune controls and other features on the F1 - F12 Keys do not work. Went into Keyboard Preferences and selected and deselected the ... [ ] Use All F1, F2, F3 keys as standard function keys. Regardless of the setting, the volume controls do not work. Even when holding down the [Fn] Key I can adjust volume with the mouse ( new Magic Mouse ) using the control on the menu bar. ANy ideas ???? THANKS !!!
