OK, I know everyone uses MN differently. I use my laptop and a Chrome browser. Usually I open Talk/Last Day and it brings up a big list of all posts in the last day for all the topics I haven't hidden). So if it is 8am, the list starts with posts up to 8am and I just use the back button to return to the list which doesn't change. For the last couple of days when I use the back button the list has refreshed itself in real time so the posts keep re-jumbling themselves into a new order. Previously I could scroll through the list in order and the post at the top would still be the same as when I opened the list - now if I scroll back to the top of the page there are numerous other posts which have appeared since I opened the site.Has something changed?
