   This is because your e-mail composing client does not conform
to the session management protocol by the gnome-session. If the client
is mozilla based, you have that problem. Mozilla has not been good
client of session management.
    gedit is a good example of fullyt compliant session client or even
gnome-terminal itself.
     libgnomeui provides a quite simple API for session manegement,
though I am sure what would happen to it after the Ridley project!

     If an application does not want to use libgnomeui for sessioning,
metacitydoes implement it own sessioning without using libgnomeui,
see metacity/session.c for details. It is quite well written :)
