Hi, Since a module nesting check has been introduced in file-mod.mkvi, the TikZ modules provoke "module wrapping error" messages in the log file. May I kindly ask the maintainer of the TikZ modules to insert the missing \startmodule command in the following files: <context-base>\tex\texmf-modules\tex\context\pgf\basiclayer\t-pgf.tex <context-base>\tex\texmf-modules\tex\context\pgf\basiclayer\t-pgfbim.tex <context-base>\tex\texmf-modules\tex\context\pgf\basiclayer\t-pgfcor.tex <context-base>\tex\texmf-modules\tex\context\pgf\frontendlayer\t-tikz.tex <context-base>\tex\texmf-modules\tex\context\pgf\math\t-pgfmat.tex <context-base>\tex\texmf-modules\tex\context\pgf\systemlayer\t-pgfsys.tex <context-base>\tex\texmf-modules\tex\context\pgf\utilities\t-pgfcal.tex <context-base>\tex\texmf-modules\tex\context\pgf\utilities\t-pgffor.tex <context-base>\tex\texmf-modules\tex\context\pgf\utilities\t-pgfkey.tex <context-base>\tex\texmf-modules\tex\context\pgf\utilities\t-pgfmod.tex <context-base>\tex\texmf-modules\tex\context\pgf\utilities\t-pgfrcs.tex Kind regards, Christoph
