I am having this same issue, I love the application but I would also
love to be able to go back and re-read old news reports.
When you go into a feed and click on a news report, it does become
grayed out; but if you press the "back" button the main screen shows
"0" for the number of items in the feed and when you go into the feed
again it is a blank screen.
Hopefully this is something you can fix?
