[NTG-context] luatex problem

Hi Hans Hi all, i use the latest context minimals under windows xp with the SciTE Editor. Since some weeks, automatic closing and opening of the PDF doesn't work anymore. My testfile pdfopen.lua has only one line: os.execute('pdfopen --file "calluna.pdf"') If I run this file with: mtxrun --script "pdfopen.lua" Adobe Reader 9 crashes completely and wants to send an error report to microsoft. If I run the same file with: lua pdfopen.lua the file opens immediately. For me it seems to be a problem in luatex. Greetings Lutz
