MiKTeX and proTeXt ⇒ "partially enabled" write18 not working?

[hendrick]

I'm running MiKTeX 2.9 on Windows XP. I want one LaTeX document, when compiled, to cause another to be compiled.

For a minimal non-working example, here is the first document, called mwe1.tex:

Code: Select all

\documentclass{article}
\begin{document}
\immediate\write18{latex mwe2.tex}
This is document 1.
\end{document}

And here is my mwe2.tex:

Code: Select all

\documentclass{article}
\begin{document}
This is document 2.
\end{document}

Running "pdflatex -enable-write18 mwe1.tex" or "pdflatex -shell-escape mwe1.tex" DOES work and does do everything I want. For security reasons, however, I'd rather not reconfigure my copy of WinEDT to always fully enable \write18.

On the MiKTeX website and elsewhere, I read that \write18 is "partially enabled" out of the box for MiKTeX 2.9, meaning that it should run recognized commands such as latex or pdflatex without "-enable-write18" or "-shell-escape". However, when I run "latex mwe1.tex" or "pdflatex mwe1.tex", the \write18 does not seem to work: I get a DVI or PDF file for mwe1, but no DVI or PDF for mwe2. The following line occurs in the .log file:

Code: Select all

runsystem(latex mwe2.tex)...disabled (restricted).

Can anyone help me figure out why the "partially enabled" \write18 isn't working for me, and help me fix it? In case it's helpful, here's the whole log file:
