Hi, and belated thanks for the replies to my question.  I agree with
both that it's nicer to have the filename in the title bar.

Both the above solutions work for me but they obviously differ in a
few ways which I am curious to understand.  The problem is I've not
yet attempted any elisp and so it's all still a bit cryptic.

Is there any relevance in the use of setq-default vs. setq?

The first solution uses (revert-buffer-function ...), and the manual
for revert-buffer-function seems to imply some relationship to dired
mode.  I couldn't see any difference between the two solutions in
dired mode.  What does this construct do?

I tried to re-order the second solution as follows, but it just
displays an "@" in the title bar:

(setq frame-title-format
  '(invocation-name "@" system-name " - " 
   (buffer-file-name "%f" (dired-directory dired-directory "%b"))))


So far all my emacs tweaks have been made through the customisation
buffers, with a little help from rtfm.  Am I right in thinking that
frame-title-format cannot be set via any of the customisation buffers?

Thanks for all your help.


Bernie.
