 Module Name:

    MaxPayne.cpp

 Abstract:

    They try to size their window to the entire screen and use the wrong system 
    metrics. This shim just redirects them to the ones they should be using so 
    the taskbar doesn't flicker through into the game. 

    This is not a Win9x regression, but since there is so much more activity in 
    the task bar area on XP, it's much more noticable.

 Notes:

    This is an app specific shim.
