Thanks a lot Taco, I'm very happy not to have wasted sunday on an obvious mistake of mine. At least I found a bug.
You can think of finding your first conTeXt bug as a kind of initiation, you are now officially anm advanced user :-)
I think I've located the file where to cut and paste the updated version (there so many ...tex postfixed files on my mac in different distribution, I don't know why. And two version of context. Who knows.).
I'm not really the right person to answer this, being a linux user myself, but I can explain the general idea. There is a file named mp-spec.mp on your harddisk somewhere (and possibly more than one). That file is indirectly used for each metapost graphic in context, because it is one of the parts needed to create 'metafun.mem', that is then itself used by mpost while creating your graphic. You need to replace the mp-spec.mp file on your disc with the one from my e-mail message, then you have to re-generate the metafun.mem file (a user on unix would execute "texexec --make metafun" for that, while being root), and finally you have to re-compile your document with it's included graphic. I cannot give you the precise steps, sorry. I hope someone else can help you if my description is not adequate, esp. on how to decide which is the right mp-spec.mp , and how to re-create metafun.mem, making sure it ends up in the right place on your disk. Greetings, Taco
