Hello out there.

Today, I got the error message "option clash for package amsmath" . OK,
documentation says this error occurs, when a package is being loaded
twice with different options. The strange thing is;

This error first appeared after I'd loaded the amsxtra-package. So I'd
guess, that amsxtra tries to load amsmath with some options but a short
look into the style-file didn't reveal anything.

Is this an known problem or does anyone have any knowledge with it?

Just for you to know why I use amsxtra:

My LaTeX-Companion says, that double-accented symbols should be defined
by \accentedsymbol. That's the way I did it.

By the way something interesting (to me)

I definded myself

\newcommand{\E}{\vec{E}}
\newcommand{\H}{\vec{H}}

further on:

\accentedsymbol{\Et}{\widetilde{\E}}
\accentedsymbol{\Ht}{\widetilde{\H}}

The funny thing know:: \Et works without any problem, \Ht throws the
eroor: "improper spacefactor". Using

\accentedsymbol{\Et}{\widetilde{\vec{E}}}
\accentedsymbol{\Ht}{\widetilde{\vec{H}}}

works fine. To me, I can't see why the one way hould work, while the
other doesn't

Thanks for your help

Alexander

By the way: Does anyone know how to make an box around a part of an
align-environment? I only need to box the first to colums or the last
line.

I'm sorry, but I forgot my header:

\documentclass[twoside,10pt,openright]{report}
\usepackage{a4,amssymb,graphics,picinpar,fancyhdr,mathrsfs,amsxtra}
\usepackage[intlimits,centertags]{amsmath}
\usepackage[latin1,ansinew]{inputenc}
\usepackage[all]{xy}
\usepackage[german]{babel}

Bye

OK. Now I understand the error. This works

The third non-comment line of amsxtra.sty:
\RequirePackage{amsmath}...

And if you would carefully look at the .log file, then you can
detect something like (pathnames stripped):
(amsxtra.sty (amsmath.sty
So you do not need any guessing, that amsmath is loaded
by amsxtra.

Solution is simple: Load amsmath with your options before
amsxtra.
