 Module Name:

    3DFrogFrenzy.cpp

 Abstract:

    Workaround for a USER bug (or by design behaviour) where if you call 
    SetCursor(NULL) and the cursor is over somebody elses window, the 
    cursor stays visible. 

    We don't normally see this because most apps that want the cursor to 
    be invisible are full-screen: so the cursor is always over their window.

 Notes:

    This is an app-specific shim.
