Opens first posts constantly. My schedule is set to 9 seconds and it's hard to even hit the configuration button. Clicking manually also doesn't help. No filter.

It happened again. It seems that when I set "Seconds between checks to move on from an empty queue" to 0, it constantly reloads any review item (<1s) and if I set it to a positive number, it opens "first posts" all the time.

Chrome on Windows 7. A relatively new version (if it didn't update itself, a few weeks old).
