Hi all,
The following example with the chemical module complains that "! Argument of
\mtharrowfill has an extra }.".
-----------
\usemodule[chemic]
\starttext
$$ \chemical{2H_2,PLUS,O_2,GIVES,2H_2O} $$
\stoptext
-----------
The result pdf looks fine, though. The annoying problem only occurs when
there's an arrow "GIVES", and only in display mode.
I am using ConTeXt 2007.08.24, and the complete warning message is
-----------
! Argument of \mtharrowfill has an extra }.

This error is due to a change that I suggested in math-ext (for over
and under arrows). I did not check that it breaks ppchtex. Here is a
fix. Add this somewhere in your style file:
\def\chemicalsingleouterarrow
{\dochemicalouterarrow
{\hbox to \dimen2{\rightarrowfill\textstyle}}}
\def\chemicaldoubleouterarrow
{\dochemicalouterarrow
{\lower.5\ht0\vbox
{\offinterlineskip
\hbox to \dimen2{\rightarrowfill\textstyle}
\hbox to \dimen2{\leftarrowfill\textstyle}}}}
\def\chemicaltwintipouterarrow
{\dochemicalouterarrow
{\hbox
{\hbox to \dimen2{\rightarrowfill\textstyle}%
\hskip-\dimen2
\hbox to \dimen2{\leftarrowfill\textstyle}}}}
Hans, this should be corrected in ppchtex. There are a few other
chemistry modules that use arrowfills, which now needs an argument
specifying the math mode in which arrow should be drawn.
I will look into it, but I have examples of working chemical
formulas.
Aditya

The fix works. Thanks a lot!
