an accdr file behaves in the same way it would for someone with only runtime access and not the full version - primarily used for development purposes since it can easily be renamed back by a user if they have the full version.
runtime access is a stripped down version and among other things does not include the navigation pane, ribbon or shortcut menus (right click). If you require these features, you need to write your own.
