This sounds like an expiry problem. In your server prefs for giganews
what do you have the expiry set to? IDR what the default is, but you can
set it to any of the dropdown choices, and if that doesn't do it for you,
you can set it to any arbitrary number of days you want by directly
editing the servers.xml file in pan's homedir[1].
