Yes, because there are two separate parts (files) per mailbox:
o Original messages (concatenated into a single file).
o Table of Contents (TOC).
A list of messages in a "mailbox window" displays info
contained only in the TOC, and that's what you must modify
(via the special extra field atop an opened incoming message)
to see the subject change in the mailbox window.
The "pencil" edits only the original message,
making a new copy in the original messages file,
without modifying any displayable fields of TOC entries.
Conversely, changes to the manually editable TOC subject field,
changes to status, labels and other indicators occur only in the TOC,
and do not affect anything in the original message content file.
