Hi Paul,
I think one should use \overline instead of \overbar in your example. For me
the following works fine with mkiv:
\starttext
\startformula
\overline{q} = \frac{\overline{q}}{\overline{α_0}}
\stopformula
In text $\overline{q} = \frac{\overline{q}}{\overline{α_0}}$.
\startformula
\overline{q_0} = \frac{\overline{q}}{\overline α}
\stopformula
\stoptext
(one gets as expected the « conjugate » of α_0, for instance).
Best regards: OK
