Does anyone have any suggestions on processing docs with many commutative diagrams in ConTeXt. Depending on the method (I have used xypic and dcpic) I can do between 6 and 8 diagrams in a doc before ConTeXt crashes reporting pdftex: Assertion failed, and Window reporting and access error. I am running MikTeX under Windows 2000. It looks like memory problems but I would like to be sure. I have not been able to find a system requirements for ConTeXt, Also, in the process of trying to work around this difficulty I have noted that ConTeXt is able to run the diagram making plain tex macros in eplain and taylor. Thanks you any info you can provide] Geoffrey Martin University of Toledo
