I'm a complete beginner with LyX, so apologies in advance if this is something that ought to be obvious. Having set the language of a paragraph to Polytonic Greek (in an otherwise English document), when I copy&paste and/or type input, then try to export as a .pdf, I get the following error message:
LaTeX Error: 'File iso-8859-7.def not found'. Can anyone tell me how to find (I think I may have) and install (no idea!) this file (or whether this is a symptom of a deeper problem)? Thanks! John
