Hi All, I'm using ConTeXt on an Ubuntu 9.10 system. $ texexec --version TeXExec | version 6.2.0 - 1997-2006 - PRAGMA ADE/POD The log file says: This is pdfTeXk, Version 3.141592-1.40.3 (Web2C 7.5.6) (format=cont-en 2009.8.3) 1 DEC 2009 15:10 ConTeXt ver: 2008.05.21 15:21 MKII fmt: 2009.8.3 int: english/english It appears connection comments do not work in this version. For example the more sophisticated example from here: http://wiki.contextgarden.net/Flow_Charts ignores the comments. See attachment (if that survives this emailing list). So basically this: \connection[rl] {lowpass1} \comment[t]{$x(t)$} \comment[b]{$X(t)$} does not work. You get the line, but not the comments. So basically two questions: 1. This used to work (Ubuntu 8.04). Is the problem solved in any newer version of ConTeXt? 2. If so, is there a way I can upgrade from within Ubuntu? -- All the best, Berend de Boer
