Hi,
I have a small lyx file. At my institute I work with 'lyx 1.1.5fix2' this file is OK; I can export it as a postscript file. At my home-PC I work with 'lyx 1.1.6fix4' and the same file gives errors when I want to export it as a postscript file. The problem is related to the classfile that I need; I use 'usepackage{notebook2e, latexsym}' but it looks like it is not found during file export. What is the correct way of including a package via the preamble? I included also the full path where the notebook2e.sty file can be found, without succes. I don't know how latex and lyx are configured at my institute but there it is enough to include '\usepackage{notebook2e, latexsym}'. The file I use at home is printed below. Who can help, thanks, Niels. #LyX 1.1 created this file.
