Hi Ruth!

Deleting the aux file before recompiling when it fails for no reason is
just one of those tricks that I've picked up on the way.

Before deleting the .aux  file, you should look at its contents.

If something is not easily readable, because it has expanded a macro
into LaTeX internal tokens and TeX primitives, or other macro names
that don't make much sense to you, then this may well indicate
the cause of the problem. Frequently it will be the last line
in the file that has unbalanced TeX bracket structures.

This kind of thing can occur when you have rather complex macros
within section titles or figure/table captions.
Often it will be fixed by using \protect  immediately before
the offending macro name, or, if it is one that you defined
yourself with \newcommand , then use \DeclareRobustCommand  instead.

Often processes
are two-stage. If you make an error that makes the compile fail, it can be written to the aux file, and ensure that, even if the original error
is fixed, it keeps failing. I thought I'd comment just to keep the
record for the future perturbed!

Gareth.


Hope this helps,
