Hello Giuseppe,

I think I found a bug in the nath module. Try the following:

\usemodule[nath] \starttext \[ e^{f(x)} \] \stoptext

And by the way, fractions in exponents are typeset too big:

\usemodule[nath] \starttext \[ e^{\frac{1}{\gamma-1}} \] \stoptext

I just hit the same bug working on my PhD thesis :) Basically, the fix that I implemented to solve the problem with ^^ not working to access arbitrary characters when nath was active causes this bug. A possible solution (as a quick hack because for the moment I can't look for a better solution) is to put \appendtoks \livesupsub@ \to\everymath in t-nath.tex after the definition of livesupsub@ and killsupsub@ Maybe Hans has some suggestion for a better solution: the problem is that the mathcode is ignored for characters with code 7 or 8 (sup- or subscript). So I'm currently changing the catcode of ^ and _ when entering mathmode. Ideas? -- Giuseppe "Oblomov" Bilotta
