Dear all, I tried to compile s-pre-61.tex to see the interaction. At the first time, I got the font error. It had a problem to use Optima-nova font. I changed the bodyfont to pagella in type-gyr.tex file and tried again. It runs without the error, but it didn't make pdf output. I checked the log file and found the following strange message (1),(2), and (3). ... (/usr/local/texlive/2007/../texmf-local/tex/context/base/type-gyr.tex) interaction : active color : mpcmyk color space is supported color : mpspot color space is supported color : system rgb is global activated system : mark Topic defined [chapter] system : mark Topicnumber defined [chapternumber] system : mark Nopic defined [title] system : mark Nopicnumber defined [titlenumber] ) systems : invalid \starttext...\stoptext structure <------------------------------------(1) systems : end file test-pre-61 at line 0 <------------------------------------(2) system : cont-err loaded (/usr/local/texlive/2007/../texmf-local/tex/context/base/cont-err.tex systems : no file 'cont-sys.tex', using 'cont-sys.rme' instead ) No pages of output.
