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.)

indeed. this is what (sort of) happens in case of a plugged in renderer:
\sqrt{#1} -> ...\mathstylehbox{#1}... -> ...\hbox{\stylecommand #1}...
when #a = a \over b the style gets applied to the a only as \over
creates two (pseudo) groups i.e. the \over isolates a and b

would work ok

Ah, I understand. The extra-braces solution, \sqrt{{k\over m}}, is
simple and I can retain my \over habits.
