When I run a minimal context file with the -synctex-switch context --synctex context-test.tex then I get a lua error: lua error > lua error on line 1 in file C:/Users/XXX/Documents/tests/contexttext/context-test.tex: ...ext/tex/texmf-context/tex/context/base/mkiv/node-syn.lua:490: attempt to call upvalue 'collect' (a nil value) stack traceback: ...ext/tex/texmf-context/tex/context/base/mkiv/node-syn.lua:490: in function 'luatex_synctex_collect' [string "local nodes_references_handler = nodes.refere..."]:14: in function <[string "local nodes_references_handler = nodes.refere..."]:7> (...tail calls...) 1 >> \starttext 2 context text 3 \stoptext Without the synctex switch there is no problem. -- Ulrike Fischer http://www.troubleshooting-tex.de/
