Navigating large-response topics
As a participant in AngryRedHead's Photo challenge, I've noticed that, as the thread gets longer, navigating it to find my past comments and replies is getting... odd.
Using the next and previous buttons seems mixed up. Sometimes you don't get a new set of comments, sometimes you get a few extra comments in between the ones you already saw, sometimes nothing happens.
Similar things happen on other topics with large numbers of responses.
