Hi all! I've just made a quick test -- running metapost with ConTeXt. The sample code was just: \starttext The simplest metapost code sample \startMPgraphic fill unitsquare scaled 123 withcolor (.2,.3,.4) ; \stopMPgraphic \stoptext which looks ok, right? And of course mpost creates nice navy square from that code. But running texexec --automprun sample.mp cause a serious system error; ''There is a problem with mpost.exe and bla bla bla''. Smart and clever' windows XP try to report that problem to microsoft. The problem occur just after terminal says This is MetaPost, Version 0.641 (Web2c 7.3.7x) (mpgraph.mp and after that system display an error box. As manual says I 've made some changes in texmf.cnf: openout_any = a shell_escape = t allow_multiple_suffixes = f What should I do next to catch 'serious system error' while running metapost code included in tex code? Is the problem comonly known? Thanks, Pawe/l
