If the file is open in Mathematica at the time that you're doing your external
edits, then you should close it.  Editing files in two different environments
simultaneously is a recipe for disaster, regardless of what software you're
doing it in.

If you're not, then you're probably just running into the issue where you're
invalidating the cache information.  If you look at the top of the notebook
file, you'll see some information embedded in Mathematica comments.  Just delete
these comments, and Mathematica will no longer try to validate the file cache.

The reason for these comments and the cache are that, if they're in place, it
can make reading the file seem considerably more efficient.  Mathematica doesn't
need the cache, but it will warn you if there's an inconsistency between the
cache and the actual state of the file.
