I'm about to have a lengthy (2,000+ page) document published. Normally if it compiles and looks okay, I regard that as meaning no errors appeared, but I've noticed that sometimes ConTeXt will still compile, even if something isn't displayed on screen as it should: (1) I tried placing a table inside a startitemize environment, as instead of it not compiling, it left a message in the document warning that wasn't supported. (2) In another case, I had an image that ConTeXt couldn't find, as I mispelled the filenmame, and it fully compiled and made a PDF, without me noticing. (3) Or maybe in some case, a font couldn't be found for a specific character, so a single character in the file isn't displaying. Those are just some examples; I intended for something to be printed on the PDF, but it isn't showing there. Since a document of this size will have a lot of messages, is there a way to adjust the settings, from "show everything" to "show some" to "show only serious errors"? Or maybe to use > to send the errors to another file for careful study? (using Linux if that matters) --Joel
