Can anyone confirm this behavior? If this is true, I don't see how it's a problem. I can only see it as an advantage.

That's what definitely appears to happen, and from my point of view it is not an advantage. Perhaps it's only a problem if you read in threaded mode as I do. I now have to wade through the threaded view working out which messages are really new and which ones I have already decided I don't want to read but are now "helpfully" marked as not read.

It is now taking me about twice as long to read each days posts. I would like the original behaviour back please, unless user options can be provided, or an alternative "up" button that does mark the whole thread/forum read.

(I have just checked the preferences screen to make sure there isn't a new config option for this, there isn't)
