There is a system event mask in low memory which is initialized to accept 
all events EXCEPT keyUp events.  This is because most apps don't care 
about when the keys are released, and keyUp events would "crowd out" other 
more important events in the queue.  You can set the system event mask by 
calling SetEventMask (see IM II, p.70).
