Graham, I would ask you to a little less obtuse to some of us who don't quite get your message. Please highlight where and in what form this 'new' button is. I cannot for the life of me find it! I am browsing on Chrome in a Windows 10 environment.
When you are seeing a list of subjects on a board, a white word "new" on a blue background appears to the right of the subject. Here's the example from my earlier post. At the time I took this screen capture, I had not read all the posts on E-scooter trails, nor all the posts on "Death on the Downs Link" so these blue and white buttons appeared just to the right of the subject.
Full navigation example:
1. Ensure you are logged in. "Unread" facilities cannot be available to guests if we don't know who you are.
2. Go to forum home page -
http://www.firstgreatwestern.info3. Select the board that you are interested in, such as "Intro and chat", "Who's Who on Western Railways", "Smoke and Mirrors" ...
4. Sticky threads, then the most recent updated thread on the board, will be displayed as per the example above, with the new button alongside any you have not fully read (or at least called up to read)
5. Click on the word "new" to take you to the older unread message in that thread
In this case, your operating system and browser should make no difference ... though stranger things have happened. If, for example, you're logged in on Firefox but visit as a guest on Chrome, then you will not get the buttons on Chrome.
