This forum is the only one whose icon on the Board Index page doesn’t change from red to blue when I mark all topics read, whether by reading them or using the link to mark them read. However, when the forums first came on line, this feature did work for this particular form. All other forums on the site work correctly.
I did that when I started reading the forums a few months ago and regularly read all new posts. Haven’t had a problem with the color of the icon turning blue after I’ve finished.
My only problem with the software is there are no Next Topic or Prev Topic buttons while looking at a message and I have to go back to the forum index to get the next topic.
