I have been trying out the newish \setupmathradical[sqrt][alternative=mp], which has been very nice because of the fine control over the radical sign. I've noticed that it crunches the denominator in \sqrt{a\over b} For example: \starttext \placeformula\startformula \sqrt{k\over m}\quad \sqrt{\displaystyle{k\over m}} \stopformula \setupmathradical[sqrt][alternative=mp] \placeformula\startformula \sqrt{k\over m}\quad \sqrt{\displaystyle{k\over m}} \stopformula \stoptext In the first line, the fractions come out fine. In the second line, the first k\over m has a small, inline-math m in the denominator but a display-math k in the numerator. The second sqrt is fine. Is the problem that my plain-TeX habits, from decades using \over, should be over, and that \frac is the recommended way? (This is with the 2014.03.27 beta.) -Sanjoy
