up2date updates exits, but icon is still blue check

[Clint <clint@xxxxxxxxxxxxxxxxxxxx>]

Updates via up2date are available and installable via the up2date icon. 
It stays as a blue check though, and does not seem to be changing to the 
red exclamation point, even though updates are available.

Here is the relevant section of /etc/sysconfig/rhn/sources file, 
including the original lines I commented out:

[...]
### Clint added the comments to the next TWO lines to try to get up2date 
to work
#yum fedora-core-1 http://fedora.redhat.com/releases/fedora-core-1
#yum updates-released 
http://fedora.redhat.com/updates/released/fedora-core-1
#yum updates-testing http://fedora.redhat.com/updates/testing/fedora-core-1

### Clint added the next THREE lines to try to get up2date to work
yum fedora-core-1 
http://download.fedora.redhat.com/pub/fedora/linux/core/1/i386/os/
yum updates-released 
http://download.fedora.redhat.com/pub/fedora/linux/core/updates/1/i386/
#yum updates-testing 
http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/1/i386/
[...]

How can I get the up2date blue check to change to red when updates 
really are available? I *thought* this feature was working a couple of 
weeks ago, but haven't noticed it changing since.

I click on the blue check once each morning, so it is getting clicked on 
once every 24 hours.

Thanks,
Clint
