It seems to work fine when using the preview pane. Reproducible: Always Steps to Reproduce: 1. Open a mail message in a standalone window 2. Hit 'F', 'B' or click "Go -> Previous Unread" or "Go -> Next Unread" 3. Actual Results: The message window loads the correct email but the main mail window does not reflect the changed selection. Expected Results: The main mail window should highlight the appropriate message after going to "next" or "previous" unread message.

I've determined that this bug does not just occur when using next "unread" and previous "unread" -- it happens when a user deletes a message from a stand alone message window and when using any of the menu items under "Go" (next/previous message, unread, unread thread).

This is WONTFIX. Since you can have 1..n standalone message windows, there's no way of doing this such that the main mail window's selection indicator provides useful information by listening to the selection from standalone message windows.

Outlook does it. So does Outlook Express. The solution, which matches intuitive expectation, is to update the main window selection to reflect whichever message is most recently updated. Consider: (a) double-click on message 1 in main window to open message window -> message 1 is selected. (b) double-click on message 3 in main window to open message window -> message 3 is selected. (c) click forward in message 1 window -> message window displays message 2 and message 2 is selected When the user returns to the main window, the selection is where he expects it to be: at the most recently opened message.
