I'm currently creating several RSS files, and all verify properly. But, for the life of me, I can't get Thunderbird to display the latest update. My other reader (Sharp Reader) will display new updates regularly. I'm wondering if it's my file and the way I'm creating it, and would appreciate any/all help anyone can shed on it.

Here are 2 URL's:

<snip>

These file are updated every hour. The first file will only ever have 1 item, as it stands now. The second file could have 1 or many, depending on the status of certain rivers.

When I create the files, I update the lastBuildDate and pubDate, but that doesn't help.

What can I do to make sure these files are updated in Thunderbird, so it will show the most recent data?

TIA!
