Thread Envelope Image Indicator Resetting?

[VulcaN]

When I post in threads and then someone else posts I see

and then once I read the latest post I see

But... sometimes I come back to the thread and see

and think oh great new posts to read! But there are no new posts, it was all a hoax

Do you have to add some kind of insane level of cookie privileges that give the forum access to my social security deposit box at fort knox for it to work properly or is something broken on the forums end?

The proper icon to note a thread has a New post since the last time you viewed the thread is this one (at least it's the one I see and instantly know there's a new post or posts in a thread that I haven't seen):

Also, note that's not the same as

which directly links to the last post made - the

specifically shows me there's something new and it takes me to the first new one regardless of how many news ones there are (they would, of course, come after that first new one if they exist).

I see the icons you're talking about but, and this one:

actually means you have a post in that thread -

means it's thread with a post or posts from you and there's a new one there also.

At least that's how I understand it. When I load a subforum I just look for the

and hit that for the threads I'm interested in to get the newest unread post(s).

I've never paid much attention to any of the other thread status icons myself, that one is the primary one I look for.
