NEWT KeyEvent Function Key Trouble

> KeyEvent[EVENT_KEY_PRESSED, code 0x69, sym 0x69, char ' ' (0x0), printable

> KeyEvent[EVENT_KEY_RELEASED, code 0x69, sym 0x69, char ' ' (0x0), printable

> NEWTEvent[source:jogamp.newt.driver.windows.WindowDriver, consumed false,
> when:1386532337753 d 0ms]]]

> I also tried outputting the value of event.getEventType() for a-z keys and
