in this particular case i do not remember, but i can say it was recently. within the last year,

sorry, i'd like explain more clearly.   i mentioned that in passing, the main point was that it was at a point in time (that i still have preserved) where either aquamacs  or my customizations.el/.emacs file/preferences.el files generated the desired effect.  i proceeded to scour each of these files (associated with the 1.5 distribution)  to see which line of code made the desired effect appear and disappear by placing them into the same files associated with aquamacs emacs distribution 1.9 on a different computer.  what i found was that the following single line of code

'(aquamacs-customization-version-id 100 t)

placed into the new 1.9 distribution on the new computer, produced the desired effect.

i figured that this line of code did a range of things.  it seems apparent to me that one of the things it'd doing is producing the desired effect just as i would like it.  i don't know how to tell what customizations this line of code does or  what further i should explore if there is a more appropriate solution.

i always keep the tabbar-mode off  with the following in my .emacs file

(if (functionp 'tool-bar-mode)
    (tool-bar-mode nil))

also i have 

 '(one-buffer-one-frame-mode nil nil (aquamacs-frame-setup))

in my Preferences.el file.
