[NTG-context] playing with Windows drag & drop

Dear list, I have a minimal sample file: \starttext \insertpages[\env{PDFdocument}] \stoptext I invoke it in Windows, using the following batch file: @echo off REM ~ context --purgeall --arguments="PDFdocument=%1" b.tex I’m afraid it only works if the batch file and the PDF document are on the same directory. I guess this is related to "\" in Windows paths. Is there a way to make it work with the sample above? Many thanks for your help, Pablo -- http://www.ousia.tk
