      Description

      Only getting keyReleased events for the compose key, not keypressed under
      hopper build 8. xev gives me both. Same bug occurs with 1.3.1 and 1.4.


      params= KEY_RELEASED,keyCode=65312,Compose ,keyLocation=KEY_LOCATION_STANDARD
      KeyChar: ? = 65535 KeyCode: 65312 Modifiers: 0
      keyText= Compose


      params= KEY_RELEASED,keyCode=65312,Compose ,keyLocation=KEY_LOCATION_STANDARD
      KeyChar: ? = 65535 KeyCode: 65312 Modifiers: 0
      keyText= Compose


      params= KEY_RELEASED,keyCode=65312,Compose ,keyLocation=KEY_LOCATION_STANDARD
      KeyChar: ? = 65535 KeyCode: 65312 Modifiers: 0
      keyText= Compose
