I am having trouble marking threads as read, and keeping to the "unread" option. I mark forums "all read", and keep electing the UNREAD option in viewing forums. But about half the time I still get threads showing up that I have marked, and my viewing frequently returns to the "recent" viewing option.
I thought maybe I had disabled cookies, but I checked and they are enabled.
I note that this problem seems to have started when the forums were revised a couple of months ago.
Any ideas?
