Hmm.. Doesn't seem to do it on my phone. On the computer every time the shout box refreshes it scrolls to the top instead of the bottom. I know you swapped it so new posts are at the bottom already... So the shout box should refresh to the bottom.
I was having issue with it using explorer, now I'm using fire fox so it works right. The new post shows up at the bottom so when you have a post with 2 lines is reads correct. the way you just swapped it to makes it read funny
