I hadn't thought of that, MJ. NoScript tells me there are 8 * scripts running on this forum. Two are "blocked as dangerous", four are "not allowed", and two are "permitted".
If I have to accept "dangerous" links to have correct links to unread posts, I'll put up with things as they are.
Do you remember which one it was that drives the "unread"?
* Ooops! Just increased to ten.
