HI! Just as the tip showed up I did the build on my ubuntu-system and along the way I also installed TL2008 and LuaTeX according to wiki http://wiki.contextgarden.net/Running_Mark_IV On running typeset in texworks it typesets and a pdf file is created but following error-message at the bottom end occurs. I did the same on a command line but there it did not show up. The errormessage inside texworks log window: mkiv lua stats : runtime - 5.414 seconds, 7 processed pages, 7 shipped pages, 1.293 pages/second ! I can't find file `./'. <*> ./ Please type another input file name: Is there something missing in preferences window? Now I have in tool configuration dialog Name: ConTeXt program: context Arguments: $fullname Thanks in Advance Janneman
