All, I have Miktex and context installed on my F: drive (partition). My path: C:\Temp>path PATH=F:\MIKTEX\CONTEXT\PERLTK;F:\MIKTEX\MIKTEX\BIN;C:\GS\GS7.04\BIN;C:\GS\GS 7.04 \LIB;C:\PERL\BIN;C:\WINDOWS;C:\WINDOWS;C:\WINDOWS\COMMAND;C:\YANDY\YANDYTEX\ ;E:\ MATLAB6P1\BIN\WIN32;C:\EMACS\BIN;;C:\GHOSTGUM\GSVIEW\;;F:\MSYS\1.0\MINGW\BIN ;F:\ IMAGINE\BIN;;E:\J2SDK1.4.0_02\BIN;E:\MATLAB6P5\BIN\WIN32 Look what happens every time I run texexec. C:\temp>texexec --version TeXExec 4.0 - ConTeXt / PRAGMA ADE 1997-2003 total run time : 1 seconds F:\Temp> The drive changes! I am using Miktex, have deleted texexec from /Miktex/bin, and have pointed my path at /Miktex/context/perltk as you can see above. Has anyone else experienced this strange behavior of changing drives?
