Bookie, ask ur brother not to log in automaticly anymore
To alter this: Tools, Options, General (tab)
uncheck "automaticly run Messenger when i log on to Windows" and also uncheck "Allow automatic sign in when connected to the internet".
By doin this MSN Messenger will not start on startup anymore...click the MSN messenger icon to start it. Note: your brother can still sign in "automaticly" meanin without typin his password by clickin on the login button and u can login underneath it (u have to type in ur password every time).
