       You will also need to make sure you change this flag yourself 
       to 1 whenever you want to redraw your object
     
       If your extension won't draw to the window, but it still needs 
       to do something every MMF loop use :

            return 0;

       If you don't need to do something every loop, use :

            return REFLAG_ONESHOT;

       This doesn't mean this function can never run again. If you want MMF
       to handle your object again (causing this code to run) use this function:

            Runtime.Rehandle();

       At the end of the loop this code will run
