<p>I tried to <a href="https://stats.stackexchange.com/questions/9033/please-help-me-remember-a-formula">edit this question</a> to reflow the formula, and noticed that MathJax stopped rendering the latex code in preview window. I use Google Chrome 10 on Mac OS X 10.6.6 Also why does this valid formula does not render (I've checked it on TexLive-2010):</p>

<pre><code>\begin{align*}
    -N-\frac{1}{N}\sum_{j=1}^N (2j-1) \left(\ln\left(\frac{1}{2}+\int_{\bar{x}}^{x_j}
\exp\left(-\frac{(t-\bar{x})^2}{2s^2}\right)\mathrm{dt}\right)\\\\
+\ln\left(\frac{1}{2}-\int_{\bar{x}}^{x_{N-j+1}}
\exp\left(-\frac{(t-\bar{x})^2}{2s^2}\right)\mathrm{dt}\right)\right)
\end{align*}
</code></pre>

<p>The problem is that it seems that <code>\left(</code> requires the <code>right)</code> without the line-break.</p>
