This is a standard technique to use when subclassing controls or other
custom views. The reason it works is because menu and control tracking
is usually done by running a separate custom event loop, and control
is only returned to the caller once tracking is complete. That said, I
think Andy's response in this same thread is better for this
particular situation.
