Extra run is needed for PDF output

[Emil Hedevang Lohse <emil@imf.au.dk>]

Hello, 

In order to reflect changes in \start/\stopuseMPgraphic I somehow need
to run texexec twice when generating PDF output.

Specifically, I have a file named fun.tex containing

\setupcolors[state=start]
\starttext
Hello, World!
\startuseMPgraphic{a}
  fill fullcircle scaled 2cm withcolor green;
\stopuseMPgraphic
\useMPgraphic{a}
\stoptext

To make a PDF file I run 'texexec --pdf fun' and I do indeed get the
correct result. However, if I replace "green" with "red" I need to run
'texexec --pdf fun' twice to make the ball change color in the PDF
file. The file mpgraph.mp is updated after the first run and does
contain "red" instead of "green", and when I view mpgraph.1 there
surely is a red ball, but somehow a second run is needed for the
graphic to be included in the PDF file.

When I generate PS files with 'texexec fun && dvips fun' only one run
is needed. I expect this is because dvips includes the updated
mpgraph.1 file into the fun.ps file.

Is there some way I can get texexec to include the graphic without
running it twice? (I can, of course, just run 'texexec --pdf fun &&
texexec --pdf fun' but that seems to be overkill.)

I admit that I have not read the whole documentation, I am just a
ConTeXt-beginner. If the information is of any help, I am running the
full installation of TeXLive 7 under Debian GNU/Linux 3.0 on the x86
platform.
