[OS X Emacs] Aquamacs and TeX-output-view-style

[Geoffrey Ferrari]

Hi, I'm using Aquamacs 1.3b on Leopard to prepare LaTeX files. I use Skim
as my pdf viewer so I have a line in my customization file (of which
more below) as follows:

;; Set the output view style to use Skim
(add-hook 'TeX-mode-hook
             (lambda () (add-to-list 'TeX-output-view-style '("^pdf$" "."
             "/Users/ghferrari/Applications/Skim.app/Contents/SharedSupport/displayline
%n %o %b"))))

This works fine for a time. But eventually, after viewing a pdf
document a few times, the variable TeX-output-view-style reverts to
the aquamacs default of "open -a Skim.app %o". I've tried
custom-setting this variable and then saving options, but that does
not prevent the problem either. Does anyone understand what is going
on, and how I can prevent it?

In case it matters, my customization mechanism is that I have my
customizations spread over several files (one for TeX/LaTeX, one for
org-mode, one for html, ...). Then, in my ~/Library/Preferences/Aquamacs\
Emacs/Preferences.el I bring in all these files via (require 'xxx).
This works perfectly on the terminal version of emacs, but perhaps not so well
under Aquamacs.

Thanks in advance for any help
