Re: LaTeX problem

I have a LaTeX file intended as a submission to an Elsevier
journal, that compiles with a spurious error. A mini-example
is at www.dieterbritz.dk/err.zip. It calls on the file
elsarticle.cls, included. When I compile it with pdflatex,
I get the apparent error
 ! Missing } inserted.
<inserted text>
                 }
l.32 \end{frontmatter}
                       ?
 but when I persist, it compiles correctly. So this is
not an error. I can't submit the paper because the journal
will reject it as having an error, so I must fix this.
What is wrong here?

Obviously a missing } was inserted. Check the file for an equal number of { and }.
