Then, Schultz bailed me out by having me move the Text-contents folder into the Text-controls folder—removing of course the corresponding ../ — and <b style="font-size: 14px;" class="">resetting something to do with \openou</b>t which I forgot long ago.<div class=""><br class=""></div><div class="">Although I don’t particularly like its lack of symmetry, I have used that structure ever since with no problem.
