When you open up a few tabs for something that requires OpenID, and sign into one of them, when signing in on the next one, it tells you that are already signed in, and gives you a "continue" button. That buttons takes you to sign in again, so it's a loop.
There may be a few different fixes for this, but one I can think of, is that the continue button take you to the page you're going instead.
