Hans, Mojca, Aditya, Wolfgang and others

1) Can anyone confirm this problem in the previous mail or point out
what might be wrong?
2) The problem Troy had with lucida, is it the same?
3) What is needed to get fourier fonts working? Is it enough adding to
math-vfu.lua an entry like
mathematics.make_font ( "fourier-math", { ...
})
with the right names for fourier? I tried this, but no math fonts is
showing up in the pdf file. In what other file should I add changes.
I'm willing to do some trial and error to get it to work...

Best regards, Mikael
