Sometimes when i finish reading a topic on the forum ,the little box with the tick on the left says that it is read (as it should be i think) but other times it comes up as not read , why is this and Is this normal.
I find that if you go back via the arrow at the top of the screen topic it will show as unread, if you go back via name of the area you are in it will show as read when you return to it.
But at times someone may make a post on the subject and then it will show unread.
