Hello All,

Running this file produces (on my system) a page with the same fore and
background graphic, i.e. the overlay graphic disappears and is replaced
by the other mpgraphic. I run the latest stuff, with all the options in
cont-sys.tex

I tried to remove the recycle slots option, but that didn't work either.

% interface=en

\setupcolors
  [state=start]

\startuniqueMPgraphic{concept} 
  draw btex \bf CONCEPT etex rotated 60 withcolor .8white ; 
  currentpicture := currentpicture ysized (\overlayheight-.5cm) ; 
\stopuniqueMPgraphic

\defineoverlay

  path p, q ;

  %pickup pensquare scaled 1pt ;
  p := fullcircle xscaled 3cm yscaled 2cm ;
  q := p shifted (x, y) ;
  draw q ;
  %draw btex name etex withcolor blue ; 
  label(name, center q) withcolor blue ;
