If I have my mails grouped by date, it is no problem deleting opened mails. Just the message window of the last mail - if it's the last one left in the "day group" - doesn't collapse after pressing the delete button in the message window.

I have to close the message window "by hand" (klicking the X), mark the mail in the mail-list and hit delete on the keyboard.

A similar behaviour with the discribed "last mail of a day" happens with the junk filter. The Mail is marked as Junk but is not removed from the mail list. I have to remove it by marking it and deleting it via  keyboard.

Reproducible: Always

Steps to Reproduce:
1. Group by date
2. Open message
3. Delete all mails in a group (today, yesterday, ...) - one by one with the delete button in the message window


Actual Results:  
Message window of the last mail of a group doesn't collapse and is not deleted in mail list.

Expected Results:  
The message window of the last mail should collapse like the others before and the mail should disappear form the mail list.

I didn't check that with other groups, yet.

This bug appears at least in WinXP SP2 and Win2000 SP4 with the latest security-patches.

Note that if you delete the last message in a group other than Today, the 
window doesn't advance to the next message (first in the next group); nor does it then respond to 'F' and 'B' shortcuts.

Reproduced with TB 2a1-0518.

With the option of displaying messages in their own window, I confirm the window does not close when deleting the last mail, but it does get removed from the list. You can try it by *starting* from the last (bottom) mail.
