when using framed texts you run into problems with flushing, struts and the nature of boxes (vbox,vtop)

in such cases one can do several things

\starttext

\showframe

\def\MyDisplayCorrection {\vskip-\lineheight}

\margintext{some text in margin}

\starttextbackground
\MyDisplayCorrection
\placeformula  \startformula  a+b=c \stopformula
\stoptextbackground

\stoptext

use a Correction macro that can be nilled (since some day we may have more control over math spacing and can fix the problem)

Here is a nice alternative:

\starttext

\margintext {some text in margin}

\setupframedtexts[background={YourTrick,MyTrick}]

\definelayer[MyTrick]

\startsetups MyTrick
\setlayer[MyTrick]{\placemargintexts}
\stopsetups

\defineoverlay[YourTrick][\setups{MyTrick}]

\startframedtext

\placeformula
\startformula
a+b=c
\stopformula
\stopframedtext

\stoptext

I'm sure that yuou can explain this on the wiki

(There is this Best Of Ruby Quiz book, maybe we should make a Best Of Context Quiz one ... )
