Status: RESOLVED DUPLICATE of bug 300749

(SeaMonkey :: MailNews: Message Display, defect)

[Claus Reibenstein]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de-AT; rv:1.7.10) Gecko/20050716 Mnenhy/0.6.0.102

When you read messages offline in an email or news folder, and you want to
change the folder, either by using the mouse or typing 'N' in a group where
there are no new messages, the new folder is selected in the folder pane, but
neither header nor message pane are updated. Even a second mouse click or a
second 'N' doesn't help. You must select a different folder with the mouse first
or sometimes even shut down Mozilla and restart it.

When reading online, this problem also appears, but not always.

Reproducible: Always

Steps to Reproduce:
1. Make sure you are offline.

2. Go to any folder and click on a message header. The message will appear in
the message pane.

3. Try to select another folder with the mouse and watch the header and message
panes. You will not succeed, even not with a second click (double click will
work, but this opens a new window).

4. Try to click on another folder and then the selected one. This _may_ work.

5. If you have unread (but downloaded) messages in any folder, select a folder
which does _not_ contain unread messages and click on any header to read a message.

6. Type 'n' to get to the next unread message, and watch the panes. Only the
folder pane will be changed.

7. Click to another folder without unread messages and try again.
Actual Results:  
Steps 3 and 6 updates only the folder pane.

Expected Results:  
All three panes should be updated.
