I found that there is a quirk with this site that whenever I finish all the threads in one forum (i.e. Vikes Talk) I need to click on the "Mark this forum Read" button. Only then will it seem to process what I have read and bring me back to the end of that each time.
I don't know why that is - but it seems to work.
After each visit, when I've caught up on all my reading, I automatically click on "Mark All Forums Read" just as a way to "clear" everything.
