why arent the topics changing shades, page-12

They way it should work is this:

If you use either single view or split view.. it loads the individual posts so they will be marked off.

If you use the thread view, it'll only mark off the first post, as you havent looked at all the subsequent posts individually.

If you hit back it will still work if you refresh your list.

The way it works is the HC site doesn't actually record visited posts differently. Its the browser itself remembering which links you clicked (ie on some sites it goes blue to purple).

So the only way to make them off is to use split or individual view and not threaded (which it uses if you click on a post if you view 1 stock only).
