Hi Hans and Mikael,
I think there is an issue with the size of math fonts in \frac when used in math alignments, as it is is shown in the following example.
%% begin bug-mathalignment.tex
\definemathmatrix[alignedcases]
[align={1:right,2:left,3:left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]
\starttext
Consider this
\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC \frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
or this (with\type{\displaystyle} added)
\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC \displaystyle\frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
Actually, one should have this
\startformula
\frac{\partial u}{\partial {\bi n}} = V u + \phi \qquad\text{on }\, \partial\Omega.
\stopformula
If one adds \type{\displaystyle} both to the numerator and denominator of \type{\frac}, the result is correct:
\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC \frac{\displaystyle\partial u}{\displaystyle\partial {\bi n}} \NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
\stoptext
%% end bug-mathalignment.tex

However, if I use \dm{} instead of \displaystyle as following, then the output is correct. \placeformula \startformula \startalignedcases \NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR \NC \dm{\frac{\partial u}{\partial {\bi n}}} \NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR \stopalignedcases \stopformula or this (with\type{\displaystyle} added) \placeformula \startformula \startalignedcases \NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR \NC \dm{\frac{\partial u}{\partial {\bi n}}} \NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR \stopalignedcases \stopformula In this example, it is OK to use \dm inside of \startformula … \stopformula. I am not sure that it is what Hans and Mikael want.

I think the correct behaviour of math alignments should avoid using additional commands such as \dm. We’ll see what Hans and Mikael say.
