Expand/Collapse Forums button not working

[Fifth Dimension]

Hi, this is my first attempt at posting here so apologies if the thread is not in the right place/my ability to explain issues is not so good.

I hust installed VB4, it's a new forum completely, and noticed that the "Expand/Collapse" feature (the small half triangle on the right side of the forum listing heading) is not working. When I click on the button, it just takes me to top of the page.

Any idea on what could be happening? Is this a minor matter, or indicative of a poor install etc?

Also -- how can we get the forum page to show the columns that previous versions of Vb would? Specifically I would like "Forum, Last Post (with a snippet of the thread title, the user who posted, and a timestamp of the most recent post made), and then Threads, and Posts". Currently it seems Threads and Posts have been combined into one column, and precede Last Post. Is there a way to edit this?

Thanks for any help...
