See screenshot below:
It took me more than 5 minutes to get that thread to be marked as read. I opened it many times, from the latest as well as the unread list, in a new tab as well as the current one.
I’ve moused over every single posting in the thread, clicked into every single one and marked some text, hit the top as well as the bottom of the page - nothing helped until just now, and I have no idea what made it work just now.
I’ve had this a few times before with different threads (most often ones where the last post was from myself), though it never took this long.
I would like to know now:
When/under what condition is a thread actually marked as read?
How do you “read” a post?
edit: ignore the blue frame; I was wondering why the OP’s avatar was missing, but that one actually is a white box.
