Hi Mikael,

Indeed your observation is correct, but using \over instead of \frac yields the correct behavior. Please try the following sample:

%%% begin derivatives-prime-4.tex
\setupbodyfont[lucidaot]

\starttext

Compare the position of the prime sign in $f'/g$ in these two expressions: the first one using \type{{... \over ...}}
\startformula
\left({f \over g}\right)' = {f' \over g} - {f \over g^2}g'
\stopformula
(which yields a correct position of the prime for $f'$ in $f'/g$), and the second using \type{\frac{...}{...}}
\startformula
\left(\frac{f}{g} \right)' = \frac{f'}{g} - \frac{f}{g^2} g'
\stopformula
which yields a prime sign for $f'$ a little bit lower.

\stoptext
%%% end derivatives-prime-4.tex
