Please describe the problem:
This is minor but makes me crazy after a while. In a newsgroup account,
I'll constantly see the group name highlighted in bold with a number of
unread articles in parens after it, but if I click on the group, the
summary that appears at the top of the sidebar will correctly indicate
no unread articles. I'll have to do a send/recieve to get the group name
back to normal non-bold, no unread article state.

Steps to reproduce:
1. Create a news account on a nntp server with fairly low traffic.
2. Read news in a group that has some unread articles
3. Mark all article read
4. Hide read articles
5. See the newsgroup name in the sidebar indicating no unread articles
6. Click on different folder in sidebar to show something else in main window
7. Click on send/recieve
8. See the newsgroup name show up again with N unread articles
9. Click on the group name to go back there again
10. See the group having no unread articles, but the group name still bold.
11. Click on send/recieve one extra time
12. See the group name go back to all read state.


Actual results:
See above

Expected results:
Clicking send/recieve shouldn't make the group name go bold and tell
me there are unread articles when, in fact, there are no unread articles.

Does this happen every time?
Yes.

Other information:
It acts a lot like the group name highlighting is somehow remembering
what the count of unread articles was the last time we were there, not
what it is based on the newest data obtained by send/recieve.

The giveaway that this is an evolution bug and not a news server problem is
the summary info for the group that appears at the top of the sidebar when
you click on the group name. The summary correctly says nothing about unread
articles, yet the group name down below is still bold and claims there are
unread articles.
