How do I prevent the frontend from modifying typeset expressions after I open previously-saved notebooks?

There are a few instances where certain examples of typeset expression are not correct re-parse when the notebook is opened. You can workaround this problem by setting the following options.

This will slightly increase the size of notebook files, but you shouldn't have this problem anymore.

If you are already experiencing problems with one notebook, you'll need to save this notebook as a completely new notebook (using the Save As command from the File menu) after making setting the option described above.

Here is one example where setting this option works around a problem in Mathematica.

If you're not using any special typeset expressions, you might have a corrupted notebook. Please see the following page for information on how to deal with this problem.
