Hello, Thank you for the new beta. I have a question about project handling. I often make the same mistake -- press compilation shortcut when a NOT main file is active. So I obtain a broken pdf and have to delete it manually. Is ConTeXt so clever to distinguish between auxiliary and main files, and use the main when I ask to compile an auxiliary? I saw some commands like \startenvironment, maybe they can help? My main currently looks like \usemodule[env.tex] \starttext \usemodule[CADD0.tex] \usemodule[CADD1.tex] \stoptext Best, Vyatcheslav
