Hi H.K.,
Thanks for pointing this out... I am indeed seeing the same thing.
Latex math-mode seems to work, but plain text is missing from the
pdf. The .tex- file is well-formatted, and I can make the pdf by hand
through pdflatex, through latex -> divpdf and through latex->dvips-
>ps2pdf. The hand-generated pdf looks fine.
Don't know what to make of it, but thanks for pointing it out.
Regards,
Michael Dugdale
