When i started up Gnome, the rhn-applet was showing in the Notification area. However, I don't use rhn, so I tried to remove it. There was no obvious way to do it, but I found a remove button in the configuration guide. And yes it worked. But only until next time I started Gnome. Then it was right back. So now I even tried to remove the rhn-applet package. But still the icon shows in the NA, but it's a question mark, and you can't do anything with it any longer. Isn't there a way to remove it?
When you are logging out, make sure 'Save current setup' is checked
I can confirm that if activating the save current setup, if the applet has been removed (or added) in the session, then the state will be maintained when login again. Works for me in the current release, Daniel
