I am not sure if login session is the right terminology but here is the problem. Every time I login as root on my FC3 machine it tends to 'remember' what apps I had opened before and opens them for me. One of these apps is gedit which has opened on it several conf files that I really don’t want to see anymore. Is there a way to kill this memory and start over or better yet just shut this feature down? Even if I shut everything down and restart the desk top and login these same apps show up. Its annoying me. Thanks in advance...

If you are using gnome. Close all applications then check the box remember settings before you logout. You should be able to then log back in without the applications restarting..

If you are using KDE,
1. Open your KDE control center.
2. Click on "KDE Components"
3. Click on "Session Manager"
In here, you will see a check box which will ask you whether you want to remember previous session, uncheck that and that should fix this little annoyance of yours.
