Well, I just tried that, and yes, it's pops back up to the very first line of what will become text in the "reply" box. It does not pop back up all the way to the top of the page, just the top of the dialogue box for replies/posts.
You're getting warmer.
There's still a problem with the quotes, too. I've noticed, as did Tvash, that after about the third or fourth time a post is quoted, the original authors become hard to distinguish, because the software doesn't attribute the quoted text to the correct author after a certain number of embedded/multiple quotations.
But when you go into the edit screen to check the tags, the "quote" and "/ quote" tags are all in the right position and embedded correctly. But when you submit and go back to the board, it's still fucked up. That's gonna be a real hard one to figure out, because it appears correct in the edit screen.
For an example, check out the exchange between me and Bug in my birthday thread. In the 15th reply (post from Bug), it appears correctly. But in the 17th reply (from me back to Bug), it's all fucked up and the attributions appear to be reversed as to who posted what. This is happening all over the board when the number of embedded quotes reaches about the fourth reply.
