Comment 27 for bug 1653351

I'm having exactly the same problem. My settings are:

* I'm using IMAP
* Client is Eudora OSE 1.0
  Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.9) Gecko/20100722 Eudora/3.0.4
* Message Pane is OFF
* Under "Options" -> "Advanced" -> "Reading & Display"
  - "Open messages in:" is set to "A new message window"
  - "Close message window on move or delete" is checked/activated

When I double-click on a message in order to read it, and then delete it afterwards, it opens and displays the next message in line in the same window. But I just want the message window to be closed when I delete the message (just like the "old"-eudora versions did years ago).

As mentioned before in Comment 19, I can't see what the function "Close message window on move or delete" does exactly either. No matter if this option is selected or not, the message window will never close on delete. I've also tested with "Open messages in" -> "A new tab" (I know, that shouldn't work at all according to Bug 531534) and "An existing message window". Everywhere the same behaviour... the message window never closes. That's very annoying...
