It definitely should not do this!

If you can't diagnose the problem yourself (see below), perhaps you
could send me a copy of your project so I can try and track it down.
If you can cut it down to a minimal example, that would be even
better.

probably right about the cause of it, too. I would guess that the
compilation process is changing a file, which is triggering a new
compilation, and so on. My code is supposed to detect this situation
and not go into a loop, but it sounds as though it isn't working
correctly with your document.

If you set TM_LATEX_WATCH_DEBUG (I assume your version was a typo!) to
anything at all, debugging messages will be printed to the system
console. Early versions had an option to display debugging messages in
a series of dialog boxes, which it looks as though you were trying to
invoke, but that option no longer exists. You can see these messages
using /Applications/Utilities/Console.app. They should tell you why
the project is being recompiled, so you should be able to tell which
file it thinks has changed.

Let me know what you find. Sorry about the problem.
