Over the last few days I've noticed that this icon keeps turning up on loads of threads which I've certainly read and have not been added to for many days. If I trawl through them I then see the No New Posts icon. On other occasions (such as just now) the icons reflect what I've looked at and what's new. It doesn't really bother me that much but it can be a bit tricky with slightly dodgy eyes to see the "last post" date to check if there's anything new I want to read. Anyone else get this gremlin?
