Michael, I fear that you are wrong. $\widehat{c}=\widehat{d}$ *is*
correct and *looks* correct. Please try $\widehat{X}=\widehat{Y}$ too
and you'll see that it *has* to be done this way.
However, what IMO is incorrect is the output of $[c = d]$. On the
other hand, $[\mathrm{c}=\mathrm{d}]$ looks ok.
\documentclass{article}
\parskip=2ex
\begin{document}
$\widehat c =\widehat d$ \par
$\widehat X =\widehat Y$ \par
$[c = d]$ \par
$[\mathrm{c}=\mathrm{d}]$
\end{document}
Regards,
Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
