unpredictability of key_press_event and key_release_event

["Christopher T. Lansdown" <lansdoct screech cs alfred edu>]

Hi,
        Is there any rhyme or reason to when key_press_events and
key_release_events come in?  Sometimes when a key is pressed, the
key_press_event comes in, other times it's a key_release_event.  Very often
when pressing a key, releasing it won't generate a key_release_event.
        What on earth could be causing this?
