You should stop using MESSAGE_MAPs.  I already explained to you earlier that
they do not work for threads.  Sending messages to threads is not handled
the same way as sending mesages to windows/components.

TThread derives from TObject, which already has a Dispatch() method.  If you
are going to makeshift your own MESSAGE_MAP, then you should name your
dispatching message to something else.

Did you actually create the message queue before trying to use it?  Call
PeekMessage() before entering your while() loop:

    PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE);
