If you use BottomFeeder, and you like the Newspaper view, you've probably run into a bug where selecting a feed can lock the application up. As it happens, that turns out to be a fairly stupid bug on my part - and it's now fixed. If you use the update tool, (third toolbar item from the left), just grab the "BottomFeeder" update and have it load without restart. It should all be good after that.

Hat tip to Michael for his help, and to Terry Raymond for pointing me to the bug.
