Re: [OS X TeX] Non–Recovery from Error

As a practical suggestion, I do a "typeset" quite often when I am entering any macros or equations.
That way, when the problem you mention occurs I know exactly where to look for the syntax error.
Often I will enter a complicated equation incrementally, starting with just the brackets and then adding the
remainder of the structure, doing a "typeset" with each addition to catch any syntax errors early when they are easy to spot.

When I do have to remove .aux files, I find that texshop brings up the viewer on the incorrect page on the first "typeset".
The second "typeset" brings me back to where I was and want to be. If anybody has a workaround on that
little annoyance I would appreciate it.

As a simple example of the behavior, suppose I forget a $ sign in an in–line expression within Foucault.tex. TexShop shows me the error in a Console window, of course. But, when I correct the error, save the source, and try to compile again, I still get and error albeit a different one:

Clearly, something is hosed in Foucault.tex but I have no idea what it could be.
