Hi, in TL 2013 neither \setupbodyfont[lucida] nor \setupbodyfont[lucidanova] works. The first one gives: !LuaTeX error: Invalid local font in font lbr! ==> Fatal error occurred, no output PDF file produced! and the other one complains about ! Math error: parameter \Umathquad\displaystyle is not set. (I've set "export TEXMFLOCAL=/path/to/texmf/with/both/lucidas".) When trying the same with latest distribution I get ! LuaTeX error .../context/tex/texmf-context/tex/context/base/math-act.lua:101: attempt to perform arithmetic on field 'size' (a nil value) stack traceback: .../context/tex/texmf-context/tex/context/base/math-act.lua:101: in function 'mathematics_checkprivateparameters' [string "local mathematics_initializeparameters = math..."]:10: in function 'runner' .../context/tex/texmf-context/tex/context/base/math-act.lua:39: in function 'assignmathparameters' .../context/tex/texmf-context/tex/context/base/math-vfu.lua:917: in function <.../context/tex/texmf-context/tex/context/base/math-vfu.lua:537> (...tail calls...) .../context/tex/texmf-context/tex/context/base/font-def.lua:423: in function 'read' .../context/tex/texmf-context/tex/context/base/font-ctx.lua:947: in function 'definefont_two' [string "\directlua "]:1: in main chunk. system > tex > error on line 52 in file /Users/mojca/context/gnuplot/mojca/texmf/doc/context/third/gnuplot/gnuplot-context-doc.tex: LuaTeX error ... and with lucidanova I get the same error as in TeX Live. I'm using \sometxt{} inside metapost code to draw labels, so maybe that's connected. Mojca
