Just today, when I go to a thread, read it, then go back to the main threads page, the title of the thread changes colour to show I've looked at it, which it has always done.

Then, it would change back to the original "unread" colour, if someone else posted to that thread and I hadn't gone back and read their posting.

Today, the threads someone else posts to after I've been there, are not changing back to the original colour to notify me that there are messages I've not read.

Does this all make sense to someone? Is there an easy fix?

Thanks,

kat
