[TxMt] LaTeX Watch / Beamer conflict

[Piero D'Ancona]

Hi
(I'm preparing a talk so I am actively testing
and running into problems, sorry...)

Again on the issue LaTeX Watch-Beamer:
could someone please reproduce the following issue:

- save a file containing only

\documentclass[10pt]{beamer}
\begin{document}
  aa
\end{document}

- invoke LaTeX Watch
- modify something (add "bb") and save
- check what's happening: on my computer,
the .aux and .pdf files are refreshed twice
a second! in other words, LaTeX Watch
continually updates even if I change nothing
(after the first change and save)

I guess this is a conflict with the pgf package.
But how? This is especially annoyng in
case of errors since the requst to show the log
is repeated every second or so...

Thanks, 
Piero
