The 'page change' function is still definately messed up for some reason. I noticed it a few days ago too.
For instance, I still can't go backwards (or forwards) on adywan's ESB:Revisited thread whenever I get to the bottom of a page, and have to scroll back up to the top to do it, as the function is still okay there.
Strange thing is, it seems this is the case on other topics too, yet some others are unaffected.
