My Mac decided it didn't want to talk to the wifi for no particular reason, and despite me manually reconnecting ot wifi this seems to have confused Usenapp enough that it has got itself stuck trying to download headers. Log snip:

Currently all subscriptions are showing an empty curcle in the Subs sidebar, and the status bar says "Downloading headers" with a spinner. Pressing "Get latest" or waiting ten minutes changes nothing except the countdown timer.
Clicking around purposefully, and it un-wedged and downloaded new headers when I clicked on the "disk free" counter at the bottom left. Unless it was just a coincidence? It doesn't seem to be an active area now...
