Only enqueue one event at a time per iteration of your main event loop (i.e. don't
enqueue events in a loop that way) or else you risk overflowing the queue. And be sure
to zero out the entire event structure (e.g. using memset) before calling
EvtAddEventToQueue. The specifics of which fields to set for each event depend on the
event type.
