I have the dec 03 t-nath and version 2003.12.10 ConTeXt.

for the first line I get

y=(1 + a/b)

what I get for the second line is hard to type, but it's what you would
expect from
$y = (1 + a\frac{b}{)}  $

so it's as if it's screwing up the arguments:  looking for three of them,
putting the first in front of the fraction, the second in the numerator and
the third in the denom.  I've tried several different examples.  They all
behave exactly as if the arguments are munged in this way.

I must be doing something wrong.  But I cut and pasted the code from the
e-mail I sent out and processed it, and I got the error I describe.

If I run it through LaTeX, I get what you describe (and what one would
expect).
It's odd that we get different results. FWIW  I'm on WinXP using MikTeX but
with a ConTeXt from pragma-ade installed in localtexmf.
Oh ... I get the same wrong result on Mac OSX/teTeX/brand new ConTeXt.
I must be doing something wrong.  Clues?
