There is a bug in some of the source code disks for microemacs 3.8 which
I have sent out, due to an error in the definition of StdText in the
Phone Book edition of Inside Macintosh (and due perhaps to my failure to
look it up in the latest edition!) This bug results in text drawn on a
Mac II screen being zero pixels high. If I had a Mac II, I probably would
have noticed it, sooner or later, myself!
