I found a document that hopefully will end this discussion:


IMHO, a relevant part from that page:

    Shutdown Notifications

    Applications with a window and message queue receive shutdown
    notifications through the WM_QUERYENDSESSION message. These
    applications should perform any required cleanup while processing
    this message and return TRUE to indicate that they can be

    Applications should not block system shutdown unless it is
    absolutely necessary to prevent corrupting the system or media
    that is being burned.

    Applications that have unsaved data ***could save the data to a
    temporary location and restore it the next time the application
