Dear all, I tested presentation mode with "pre-green" module and it worked fine. I also tested the same file with the addition of few lines which set my personal font script for XeTeX-ConTeXt. \usetypescriptfile[type-xkor] \usetypescript[myface] \switchtobodyfont[Myface, 12pt, rm] Save the file(utf-8) and compiled it and I got errors: (/usr/local/teTeX/share/texmf.local/tex/context/base/type-akb.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-xtx.tex) (/Users/dalyoung/Library/texmf/tex/xetex/type-xkor.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-exa.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-syn.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-enc.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-dis.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-siz.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-map.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-spe.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-akb.tex) (/usr/local/teTeX/share/texmf.local/tex/context/base/type-xtx.tex) (/Users/dalyoung/Library/texmf/tex/xetex/type-xkor.tex)) (./context- pre.tuo) Runaway argument? {^^G^^[⻊\usedmapfile {=}{original-base}\usedmapfile {=}{ec-public-l \ETC. !
