I'd say about 1/3 of the time, I click New Posts and it goes back to some time yesterday or the day before. I know I've hit mark Forums Read before leaving the previous time.
OK, I think I found the issue that causes it not to work.
I have a few forum members on my Ignore list. When one of them makes a post, the "mark forums" read flag seems to be blocked in those threads with Ignored posts.
