I just had it on one of the threads again but not another one. It just started several days to a week ago (I didn't keep track) and if I'm on either the iPad or iPhone it's really annoying, but on the desktop I just hit Ctrl End and it goes to the bottom then I scroll up to see where it started. I haven't done anything that I know of that would change anything. If it were just on the Apple products I would think it was an update there, but it also does it on my HP.
