Have a Gateway 200 Arc laptop. Several keys on the keyboard are displaying the fn output as if I were pressing the function key with it. i.e. if I press the "U" key I get a "4". If I press "FN + U" I get "U". I have tried uninstalling and reinstalling the driver without success. I also tried using keyTweak to remap the keys but when I go to apply the settings I get the following error "No current mappings in registry currently". This problem started after I plugged in and used a USB keyboard. Hope you can help.
