I haven't downloaded it yet but I appreciate the reassurance (10.4.11)
—as well as the explanation—and, in any case, I wish to join the
crowd and thank Koch et al for a front end that I have really enjoyed

P. S. Last night, I spent a couple of hours on acquamacs because I am
looking for an html editor and thought I would first meet acquamacs
