I think it's been within the past 1 to 2 weeks that I've noticed this odd behavior. If I open a series' main page, or return to it after finishing the most recent chapter, the page automatically scrolls down to the last comments just above the field for creating a comment of my own. I don't know if this is new site behavior, or something strange on my end. I tried deleting cache and cookies, but the behavior persists. I've just now seen that it will do the same thing in forum topics, where the page will scroll down automatically to the reply box.
Thanks for your time.
