Question re: Unread Posts

[KJS]

How come when I choose to view a thread I have never opened it does not always open to the original post?

The software seems to have some state of "first unread post" that is not related to the user. I read in flat mode and I would expect that every topic I have never viewed, regardless of how many replies, would open to page 1. But it does not. It seems to open at some "first unread post" that is often somewhere many pages down. Then I have to go to page 1 to read the OP and the replies from the beginning.

For instance, there is a thread in OOT called "Perfect MCAT Score". For replies it says 54(2) for me. I am 100% certain I never opened this thread. But my guess is that if I did, it would open to the 2nd last post (first unread, but by whom?) not the OP.

Just curious why this is and if there is a setting I can change on my preferences so that threads I have never opened always go to the OP when I click on them for the first time.

Thanks.
