Dear List,
i have the little following example:

\setuppapersize[A8,landscape]
\setuplayout[leftmargin=2.5cm,
             leftmargindistance=0.2cm,
             backspace=2.9cm,
             width=4cm]
\showframe
\starttext
\blackrule
\margintext{Me}
\blackrule[color=black, height=0.5ex, width=1cm]
\stoptext
\startformula
a^n + b^n = c^n.
\stopformula
\stoptext
What i want is a\blackrule over the margintext, but i do not get what I wantend.
