Hello list, About two months ago (2020-08-26) I described a difference between LMTX and MkIV in the setting of index registers entries, and more particularly, in the trimming of text to fit the available width therein. I have now created a smallish example to demonstrate the problem. I do notice that the problem is very sensitive to the width settings, and slight variations in width create different results with both engines. This ConTeXt input: \definepapersize [pinched crown quarto] [width=6.69in, height=9.61in] \setuppapersize [pinched crown quarto] \setuplayout [width=fit, backspace=1.4in, cutspace=1in, leftmargin=0.65in, rightmargin=0.65in] \setupregister [index] [n=2, balance=no, maxwidth=4cm] \starttext \startchapter[title={Index Test}] \index{Anonymous+Felix quem faciunt aliena pericula cautum} \index{{Diderot, Denis}+Et des boyaux du dernier prêtre, Serrons le cou du dernier roi} \index{{Dunne, Finley Peter}+Thrust ivrybody, but cut th’ ca-ards} \index{Eisenhower+Dwight D.+influence … by the military-industrial complex} \index{Eisenhower+Dwight D.+plundering, for our own ease and convenience, the precious resources of tomorrow} \placeindex \stopchapter \stoptext produces, with MkIV: and with LMTX: The example code shows one other instance as well, in the fourth indexed entry. Beside looking uglier, this results in a couple more pages for the same number of index entries. As I noted in my first description of the problem, this may not be unique to register processing, and perhaps it is an issue with limitatetext or doboundtext, or something else entirely. -- Rik
