This is great. It seems to respond about like the old version.
The only "odd" time it refreshes now is when I returen to "latest posts", even if it has not changed. The old forum used to leave this alone (retrieve from cache) as I worked my way through the posts, then I would click latest posts when I got to the top of the list.
I realize that this means the most current posts would not be displayed, but in fact, updating this screen causes the highlight, showing the last thread accessed, to move up the list by one place for each new post.
As usual, the good of this forum, thanks to your efforts, far outweighs any of my irritations, so just keep up the good work and don't put yourself out trying to make me happy.
