They don't reappear on the list. But the little red icon pops up again and it's the same change to the thread as before. It happend on the Indian P/Q/R discussion when FB and GermanF1 were talking about dust and smog.
That'll teach me to read stuff properly. I'm tired and having just read your post in this thread when I followed the later alert and just glanced at it so it looked like the same post and I thought ... wha' TF? . I'll go back and read it now. Doh!
Nah Fenders, i haven't had the problem in a while, like I said it was when Ray posted I would see his posts, then 10-30mins letter get another alert saying new post from Ray when it's the exact same post! (could be because of the different time zones, i have one of my own ) don't use the back button, I click on the trusted refresh option
