TA, I really hope this is a bug and not something new...
If you click on the forum breadcrumb link above a post/forum, it creates a drop down box instead of taking you to that forum.
Forums > New York Forums > New York City Forums
If you click on the third link, whereas you used to get taken to the first page of the NYC Forum, now it creates a dropdown. This is totally frustrating. I am guessing you are supposed to get the dropdown only if you click on the arrow to the left of 'Forums' - but clicking anything gives you that box.
