[OS X TeX] \input and Texroot

I am experiencing a problem for which I don't know how to provide a minimal example, and have no idea even where to look for a cause.
I have been working on a book for some time, in which the individual sections are in separate files, named <section>.tex, and the accompanying exercises in files named <section>.ex.tex.  The master file, CalcThree.tex, calls them via \input{<section>}
(resp. \input{<section>.ex}).  Each of the individual files starts with
%!TEX root =  CalcThree.tex

All of these are in a single folder.
I had a fully functioning version of this book, but need to do a major rewrite/revision.  So I created a new folder, and am one-by-one duplicating the section files, moving it to the new folder, renaming the file <section>.tex copy (reps. <section>.ex.tex) as  <section>14.tex (resp. <section>14.ex.tex), changing the root to
%!TEX root =  CalcThree14.tex
changing my \input calls, and doing my revisions there.

All was going fine until I got to the exercises for the fourth section, originally in file dot.ex.tex.  I have the following weird situation: if I hit the "Typeset" tab from file dot14.ex.tex, the compiler works away on compiling the book until it gets to \input{dot14.ex} where it stops and gives me the error message: can't find file dot14.ex.  Same if I typeset from CalcThree14.tex.

What can possibly be going on, or more to the point, how can I work around this?  I've tried various versions of explicitly adding the .tex to calls, renaming the file, etc., all to no avail.
