I don’t know.  I work from two computers, one at home and the other in my office, so for years I have used Dropbox to synchronize files that I might want to access on both.  I had someone else set up things so that I had my macros in one place to use for both.
  What puzzles me is the different behavior of this one file, when the setup has not (to my knowledge) changed.  I don’t think I want to mess with it.<br class="">

<div class="">I have been generating a set of TeXed homework assignments for a course (Math 135), trying to make it stand-alone so that others teaching the course could use my .tex files.  I habitually use a lot of macros, and have several extensive files of
 user-defined macros.  So far, I have been copying individual </div>
<div class="">macro definitions into the .tex file for each assignment, but this has proliferated, and I have finally decided to create a dedicated macro file for this purpose (to include whenever I distribute the .tex files for these assignments), called 135HWMacros.sty.
  I created this by copying the list of \newcommands from the latest assignment into a new file in TeXShop.  When I tried to save it as 135HWMacros.sty, I was not allowed to (I was told to use 135HWMacros.sty.tex).  Now, I have a folder in Dropbox called Macros,
 with a subfolder called MyMacros, where I keep all of my older self-defined macro files.Things are configured so that when I compile a .tex file this folder (and subfolder) is searched first for macros.  When I saved my new file there as  135HWMacros.sty.tex,
 I would get an error saying “can’t find file 135HWMacros.sty.  Of course—in fact, the icon for that file was different from those of the other style files there.  So I renamed it 135HWMacros.sty (having saved it there earlier with the longer filename.)  But
 now I still get the same error message.  What should I do (or have done) differently?<br class="">
