# [OS X TeX] A bug in TS?

Hi,

I am using TeXshop 2.18 on  a Powerbook running 10.4.11. When I
typeset the following sentence, a leading "1" in the formula is left
out:

The damping time is $1/\zeta\omega_n=(1/\tau+\sigma\Gamma n_0)/2 \approx 10^{-9}~\mbox{s}$.

However, when I put a space after the first \$, it works correctly. I
typeset the same document on a Latex machine (using Kile) and it
worked properly without the space (as it should). In other cases,
leading characters in online equations usually do not cause problems
(it failed in another case with a leading numeric).

When I use the LateX Equation Editor, it works fine, so it is not the
TeX engine, apparently. Also, in a fresh document, things work properly.

Does anyone know what is going on?

Thanks.
