Do you mean pen up and pen down when you say key up and key down?
The key events are the arrows and the four app buttons.
If you do mean pen when you say key ... are you returning "true" or
"false" for handled from the event handler for those events. If you
are returning "true" then the OS will do no further processing for
those events because you have told it that you've done everything
required. If you want the OS to do hit testing, return "false" from
the event handler for the pen events.
