My new ConTeXt Mark IV hangs at the first \in it encounters, this is the error message: ! LuaTeX error ...text/tex/texmf-context/tex/context/base/strc-ref.lua:656: attempt to index field '?' (a nil value) stack traceback: ...text/tex/texmf-context/tex/context/base/strc-ref.lua:656: in function 'resolve' ...text/tex/texmf-context/tex/context/base/strc-ref.lua:735: in function 'identify' ...text/tex/texmf-context/tex/context/base/strc-ref.lua:947: in function 'doifelse' <main ctx instance>:1: in main chunk. system > error on line 31 in file intro/intro.tex: LuaTeX error ... If I comment out all references, the file compiles without problems. Mari
