Status: VERIFIED DUPLICATE of bug 123858

(SeaMonkey :: MailNews: Message Display, defect)

From Bugzilla Helper:

Viewing news as threads. Click the + button to expand; then click the first
entry in the thread. Immediately after message is displayed, the - button
changes to a + button. If you now click the erroneous + putton, the remaining
entries in the thread are duplicated.

Reproducible: Sometimes
Steps to Reproduce:
1.Select threads in news display.
2.Click + button to expand the thread; + changes to -
3.Select the head message in the thread.


Actual Results:  The "-" (collapse) button turns to a "+" (expand) button
immediately after the selected head message is displayed. If you now click the
erroneous "+", expansion takes place; the non-head entries in the thread are all
duplicated in the display.

Expected Results:  The "-" button should remain a "-" after the head entry is
selected and displayed.

Sometimes, this works o.k.; but usually you get the behavior noted. If at first
you don't succeed, keep trying; eventually, the behavior will start and will
continue.

You can avoid this duplicate entries display if you select the head message
before expsnding the thread. Everything will work as expected.

Once you realize what is happening you can just ignore the behavior; you are
able to display all messages and the duplicate display disappears the next time
you open the news.

The behavior noted only occurs when the entire thread is unread.

Thanks! Yes, this is a duplicate of bug 123858, especially comment #9 with two
comments:
On occasion, I'm sure I've had the bug go away. Probably after a clean install,
but it always seems to come back.
And I'm a little amazed at how people's perceptions vary. I was hesitant to
submit the bug since it appears to be non-harmful, just a minor annoyance to me.
Others see it as a major problem! Guess I'm easily pleased. :)
