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).

Dear ConTeXt folks,

I do have some problem with the following example (also attached, executed with `context test`).

\starttext \startformula \overbar{q} = \frac{\overbar{q}}{\overbar{α_0}} \stopformula In text $\overbar{q} = \frac{\overbar{q}}{\overbar{α_0}}$. \startformula \overbar{q_0} = \frac{\overbar{q}}{\overbar α} \stopformula \stoptext

I am using the latest ConTeXt Minimals distribution.

1. The bar divides for subscripts/indices. 2. If you look at the first fraction, the bar is as long as the stroke from the fraction and therefore I think too long. 3. When inlining the fraction in text the bar fuses with the stroke from the fraction.

Are these know problems or do I just use the wrong commands?

Thanks,
