This has started a couple of days ago. I used to have a 'clean' home board where all the discussion categories would show a NEW logo if I had missed a post and not viewed it. I don't read everything, but I check each post / thread just to keep the main board clean. When I click on a sub-cat, I used to see topics highlighted in blue to indicate I needed to view a new post. This is no longer happening for every post, although it does for some, and I have recently had to physically read the date / time of a post to discover it is new. Additionally, I now find the NEW logo above a sub-cat doesn't always disappear, even if I have read each new topic. Am I alone in this ?
