binom, dbinom, and tbinom LaTeX commands display incorrectly

[Patrick]

When I enter something like <latex>$\binom{n}{x}$</latex> into the
question or answer field, the result is identical to that obtained by
entering <latex>$nx$</latex>. Instead of displaying the "n" on top and
the "x" below, Mnemosyne displays them side-by-side without any
parantheses. This is the first problem that I have encountered in the
twenty or so equations I have entered. I am using Windows XP and
MiKTeX 2.7, and am running Mnemosyne as a portable installation.

[Peter Bienstman]

\binom is not standard latex, but part of the amsmath package. Edit
.mnemosyne/latex/preamble to read

\documentclass[12pt]{article}
\usepackage{amsmath}
\pagestyle{empty}
\begin{document}

BTW, you can simplify your tags to read:

<$>\binom{n}{x}</$>

Cheers,
