Hi, The following used to work: \startMPrun{foo} beginfig(1); fill fullcircle scaled 1cm; endfig; \stopMPrun \starttext \externalfigure [mprun:foo.1] [width=4cm] \stoptext now I get: ! LuaTeX error ...ext-beta/tex/texmf-context/tex/context/base/grph-inc.lua:690: bad argument #1 to 'isfile' (string expected, got nil) stack traceback: [C]: in function 'isfile' ...ext-beta/tex/texmf-context/tex/context/base/grph-inc.lua:690: in function 'locate' ...ext-beta/tex/texmf-context/tex/context/base/grph-inc.lua:922: in function 'identifier' ...ext-beta/tex/texmf-context/tex/context/base/grph-inc.lua:940: in function 'identify' [string "\directlua "]:1: in main chunk.
