If you set 0 as the time out parameter (which happens to be wait forever),
EvtGetEvent will not return a nilEven unless the UI has generated it.
NilEvents are not generated while the pen is on the screen. What you may
want to do (since you need to trigger on events often) is to look at all
events, not just nilEvents. That way, you may get a few extra ticks while
the pen is in use.
