OK. Thanks for the feedback. We will now incorporate the changes to
the original packages and commit to SVN.

jsMath does not seem to support \intertext command. It throws an error
"unknown control sequence \intertext" when \intertext is used. We have
circumvented the problem with \text command instead which won't give
the right kind of rendering you would expect although it can pass
through the output creation process silently.

That will be the best, Rob. jsMath needs to support \intertext.

Best regards
