When LoadMXfile is used the user may be prompted for a password; refer to the tables below to determine when this may occur. Additionally, password prompts may be given if accessing MapDocuments using either the MapControl's PropertyPage, ArcMap or ArcReader; the tables also show in what circumstances this will occur.
