Description of Problem:

If a message is being viewed in a separate window and it is deleted
(through either the button or Control-D shortcut), the next message in the
folder is shown in the same window.  It would be nice to have this
configurable to close the message window and return to the main folder
listing.  This is useful if one bounces around a mail folder rather than
reading messages sequentially.


Steps to reproduce the problem:
1. From a folder list, double click to open a message.
2. Press Control-D to delete the current message.

Actual Results:

Next message is displayed in message window.

Desired Results:

Message window closes and folder listing window is given focus.

How often does this happen? 

Always in current version.
