Description of problem:
The rhn applet icon displayed its red exclamation point, indicating the machine was out of date.
I clicked on the rhn icon and successfully downloaded and installed available updates.
Following completion of the updates, the applet icon image changed to a gray question mark.
Allowing the mouse pointer to hover over the icon displayed the message "Error connecting to RHN...".
When I clicked on the icon, an exception message dialog appeared. Following is the text of the message:

=====================================================

After closing the dialog the rhn applet icon changed to a blue check-mark. Allowing the mouse pointer to hover over the icon displayed the message "Waiting before checkin...".

About a minute later, the icon changed back to the gray question mark and the same exception was raised.


Version-Release number of selected component (if applicable):
rhn-applet-2.1.17-5

How reproducible:
Always

Steps to Reproduce:
1. Click on rhn icon when it's red.
2. Download and install updates.
3. Click on rhn icon when it's gray.
  

Actual Results:  Applet exception was raised as described above.

Expected Results:  The applet should change to blue check-mark and remain that way until updates are available.

Additional info:

A nearly identical server with an identical RHEL4 installation in another building (using a different Internet connection) does not exhibit this behavior. Each server connects through the Road Runner Business Class cable internet service in the building in which it resides.

I have submitted this exception twice to applet.com as requested but never got any feedback.
