Forum "Read" mark problems

[Crumm]

What this means now is that if you log on and there are 200 unread posts and you only read 50 of them and log out, the next time you come back the remaining 150 that you didnt read will probably be marked as "read".

Thats how it is once again. I really liked the way you had it for the last few days. No way to make it work?
