# Using \jot crashes \intertext’s spacing

As mentioned in Intertext vertical spacing, there seems to be some inconsistencies in spacing around AMS’ macro \intertext, even without changing the length of \jot. But if I’m using a longer \jot to get mor space between equations in array, the problem gets a real problem.

This is an example showing the problem:

\documentclass[11pt,fleqn,ngerman,DIV=8]{scrartcl}
\usepackage{lmodern}

\usepackage{amsmath}
\setlength{\jot}{2\baselineskip}

\begin{document}
Text Text Text Text Text Text Text Text Text Text Text
$$m\cdot a\cdot t\cdot h = 0$$
Text Text Text Text Text Text Text Text Text Text Text
\begin{align}
m &= 0\\
\intertext{Intertext Intertext Intertext Intertext Intertext}
a &= t\cdot h/2
\end{align}
Text Text Text Text Text Text Text Text Text Text Text
\begin{align}
(a+b)^2 &\neq \left(a^2+b^2\right)\cdot\left(a^2+b^2\right)\\
&=\left(a^2+2ab+b^2\right)
\end{align}
\end{document}


Does anybody know how to get exactly the same spacing with \intertext as without it?

I’m sorry … a few minutes after asking I’ve fount the solution via Google: Here one can find a package called amsmath1 which fixes the spacing problem :-)

Shall I send a bug report to AMS?

no, report it to the maintainer of mathtools so it can be fixed there. amsmath is frozen, and fixing the bug there would break a lot of existing documents. –  Philipp May 29 '11 at 12:28
@Phillipp: But then I have to load mathtoolsadditionally, right? Does it work together with the AMS packages? –  Tobi May 29 '11 at 14:02
… by now i noticed that mathtools loads amsmath so I can replace it :-) –  Tobi May 30 '11 at 21:48
… and I sent an e-mail to the maintainers of mathtools (Why can’t I edit my last comments?) –  Tobi May 30 '11 at 22:03
Update: The developers of mathtools fixed it an it shall be available in the next release this summer. (@Philipp) –  Tobi Jun 10 '11 at 9:01
