 *                parse the `lpCmdLine' param into main's argc and argv variables,
 *                start the user interface thread (for the systray window), and
 *                call main (i.e. patch execution into normal IJB startup).
 *
 * Parameters  :
 *          1  :  hInstance = instance handle of this IJB execution
 *          2  :  hPrevInstance = instance handle of previous IJB execution
 *          3  :  lpCmdLine = command line string which started IJB
 *          4  :  nCmdShow = window show value (MIN, MAX, NORMAL, etc...)
 *
 * Returns     :  `main' never returns, so WinMain will also never return.
