Hi Peter,

> I did some more testing.

I've tried to reproduce the issue with Emacs 24.5.1 and AUCTeX 11.88.4
From ELPA but I failed.

This is what I get.

\begin{itemize}
\item If you tap your finger against a bridge at exactly the right frequency,
  the bridge will collapse. (Resonance)

\item The formula used to calculate the interest rate on your mortgage is
  actually just a fancy form of the ratios of angles in a triangle. (Euler's
  formula)
\end{itemize}

And here I get this.

\begin{enumerate}
\item First item
  \begin{itemize}
  \item If you tap your finger against a bridge at exactly the right frequency,
    the bridge will collapse. (Resonance)

  \item The formula used to calculate the interest rate on your mortgage is
    actually just a fancy form of the ratios of angles in a triangle. (Euler's
    formula)
  \end{itemize}
\end{enumerate}

Here, too.

Yes.

Did you try without your AUCTeX configuration?  The filling you get
looks like you have added an entry '("enumerate" current-indentation) to
`LaTeX-indent-environment-list'.  It's possible that you had a broken
configuration before that didn't cause the issue because of an AUCTeX
bug which got fixed lately.

Bye,
