IMAP folder tree pruned

[Peter Bloomfield <bloomfld eos ncsu edu>]

Congratulations on a great mail tool!  I just upgraded to 1.1.4, and it
looks very good. However...I want to use Balsa solely to manage mail on
a remote IMAP (Cyrus) host, and I don't understand how to set this up.
I checked ``subscribed folders only'', and INBOX shows both as a mailbox
(icon = tray), and as a folder (icon = folder) containing the next level
of names.  However, these next level items are shown only as mailboxes,
even though most of them also contain further subfolders.  Console
reports begin as follows:

     [Peter@myhost]$ Opening 3 mailboxes on startup.
     Loading its configuration...
     Server loaded, host: Peter.mail.xxx.yyy, port 143
     imap_dir: reading for
     Deph: 0 -------------------------------------------
     imap_add_folder. delim: '.', folder: 'INBOX', noselect: 1
     noinferiors: 0, isparent: 0
     ADDING FOLDER INBOX
     imap_add_folder. delim: '.', folder: 'INBOX', noselect: 0
     noinferiors: 0, isparent: 0
     ADDING MAILBOX INBOX
     Deph: 1 -------------------------------------------
     imap_add_folder. delim: '.', folder: '', noselect: 1
     noinferiors: 0, isparent: 1
     imap_add_folder. delim: '.', folder: 'INBOX.Courses', noselect: 0
     noinferiors: 0, isparent: 0
     ADDING MAILBOX INBOX.Courses

Is there some setting I'm missing that will let me see the whole tree?
The relevant part of .gnome/balsa is

     [folder-0]
     Server=Peter.mail.xxx.yyy
     Port=143
     Name=IMAP
     Directory=
     Subscribed=true
     Threading=1
     SortType=1
     SortField=0

Thanks for any help!
