Hi all, When typesetting my project with interaction, sometimes the processing stops after a few runs with an error message that points at an empty line in one of the chapters that normally gives no trouble. For interaction this setup is used: \setupinteraction[state=start,focus=standard,style=,color=blue,contrastcolor=] \placebookmarks[prechapter,chapter,section][prechapter,chapter,section][number=no] When I comment out the first of these two lines, in other words, without interaction, the project is processed without any problem. Sometimes, unfortunately not always, when I immediately repeat the processing with interaction, all goes well. So what is my problem? Not understanding what might be wrong, and not being able to correct things gives me a feeling of insecurity, trusting Murphy’s law to make sure that processing will fail when my deadline is approaching fast. I use mkiv on Mac OSX 10.9.4. All my standalone versions from january up to today give the same behaviour. I mostly get the following error message: (occasionally something different happens: the processing gets into some endless loop and I have to abort it) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ tex error > error on line 2314 in file TD-Ch3.tex: !
