Count me out. :(

I get "\textfont6 is undefined" on the formula that is
supposed to work, and a nice bold dotlessi (!) on the
one that is not. (the third one has missing braces)

But then, I only added \setupformulas[method=bold] to the
example, nothing else.

This appears to work reasonably well for me:

   \startformula   % this works
   \bfmath \sin{\frac{\pi}{2}}=\sqrt{2}
   \stopformula

Cheers, Taco
