I'll try to clarify that poorly worder subject:
When I read articles via the Unread News section, they're marked "Read" as I go. The "unread count" at the top decreases as I go along... makes sense thus far.
If I choose another section (such as News or Tech), the articles I've already read earlier are not marked as "Read." If I select the All News section at the top, the unread counter at the top remains the same as when I started, requiring a Ctl-R to re-mark the items as Read and reset the counter.
Quite strange...
Cheers!
The same bug
