------------------------------------------------------------------------------- Main message procedure of the application The function handles all incoming messages for the main window. However, if does not directly process input commands. NOTE: Due to the impossibility to process WM_CHAR messages in dialogs properly the code for all hotkeys has been moved to the WndMain -------------------------
