With some help from Anthony Lander, I just found and fixed a startup bug in BottomFeeder. If you change the look and feel (not common, I guess, since this hasn't been reported before), Bf starts up looking like it's lost all the feeds, and then isn't truly functional. The problem was a timing bug that cropped up because of the new tabbing code. I have an update on the site (meaning, look for updates - there's not a new full build out).
