While true that you can derive directly from TEventHandler, OWL's message
processing mechanism uses the parent/child window relationship to handle the
(convoluted) routing of messages. Also, message queues need a window handle
for Windows to send messages to. If you want your thread to process messages
like your main window, create an invisible window in your thread. Then you
can set up a message processing loop in its Run() method.

Your class should be able to receive messages. What message are you trying
to process?
