 Module Name:

   IgnoreZeroMoveWindow.cpp

 Abstract:

   This shim changes MoveWindow calls with zero-sized width &
   height parameters to a value of one. NBA Live 99 was failing
   due to an internal check. This implies that WIN9x does not allow
   zero size windows.


 Notes:
    
    This is an app specific for NBA Live 99
