Hi Alex,

I agree that these Mathematica parsing problems are extremely annoying. I
have two suggestions. First, for your save problem where a parsing problem
appears after a file is saved, one possibility is to deactivate
Mathematica's condensing routine by setting the option ShortBoxForm to
False. Start the option inspector, and in the lookup box type ShortBoxForm.
Then set the option to False. With this option set to false, Mathematica
will not attempt to shorten the notebook, and consequently the notebook
files will be marginally larger (but who cares?). I believe that this will
take care of your save problem.

As far as invisible parsing errors which occur while you are editing a
notebook, one tedious and unattractive possibility is to always use
InputForm for your input. Mathematica should never reparse InputForm input.
However, since I like StandardForm input, my usual solution is to put in
carriage returns at various places until the error goes away.
