Dear Hans, Thank you for your answer. Since it worked perfectly before, I created XeTeX-ConTeXt format using texexec --make --xtx en for a test and run "texexec --xtx file.tex". It run OK and I got a pdf output. I think that it is not only the font problem unless texmfstart uses fonts differently. So my wonder is what cause the difference between texmfstart texexec --xetex file.tex and texexec --xtx file.tex.(no output with errors and good output). I am sorry to list this which is the problem for me only. Since my TeX-knowledge is very short, I couldn't do anyting but testing. I'll upgrade to the latest version soon and see how it runs, although I am afraid of upgrading the current ConTeXt(05-11) to the latest one. Thank you again. Best regards, Dalyoung
