The following example works on live@contextgarden, but on my computer it only writes "unknown" at the place of "x". btex etex also doesn't work in ConTeXt (metaplay) on my computer, although it does without any problems in metapost/mptopdf. \starttext \startMPpage draw textext.origin("x"); draw fullcircle scaled 2cm; \stopMPpage \stoptext I use the latest MikTeX distribution (although ConTeXt may not be really up-to-date, but that shouldn't be a problem, I suppose). It's probably just a matter of a single setting or so (it should be corrected in MikTeX as well if that's the case), but I don't know where to start looking. Thanks for help, Mojca Miklavec
