Hi, I am using Miktex (latest updated version) and the latest Context on WindowsXP (write18 enabled). This is what happens : 1) First run of texexec gives me ! Undefined control sequence l 1 \global \loadfontfileoncetrue 2) Second texexec run compiles fine, and the Metapost code is processed and included in the resulting PDF document 3) Third run of texexec same error as in 1) Looking at i.e *mptrace.tmp* file it says mpgraph:=1; randomseed:=1559; _special_div_ := 1000; if unknown context_tool: input mp-tool; fi; if unknown context_spec: input mp-spec; fi; if unknown context_grph: input mp-grph; fi; graphictextformat:="context"; *graphictextdirective "\global \loadfontfileoncetrue ";* string contextversion; contextversion:="2006.03.25 13:21"; if not known _data_prefix_: string _data_prefix_,_data_suffix_; fi; ..... Does someone know the solution to this problem ? Thanks Wim
