Dear List,
The following code draws a circle at the center of the page, ignoring
the "shifted" part.
\startuniqueMPgraphic{concept}
draw fullcircle scaled 1cm shifted (10cm,10cm);
\stopuniqueMPgraphic
\defineoverlay[concept][\uniqueMPgraphic{concept}]
\setupbackgrounds[page][background=concept]
\starttext
.
\stoptext
How should the metapost background figure be positioned correctly?
\startuniqueMPgraphic{concept}
StartPage;
draw fullcircle scaled 1cm shifted (10cm,10cm);
draw Page withpen pencircle scaled 5mm;
StopPage;
\stopuniqueMPgraphic
