 Module Name:

    HPTourGuide.cpp

 Abstract:

    The application causes Explorer to crash when
    a tour is selected. To fix we are eating LVM_GETITEMA
    messages if the window handle matches the ListView
    that the app was sending to.
    Fix for Whistler bug #177103
    
 Notes:

    This is an app specific shim.
