Michael,
Do you have any trouble printing (generating pdf files) using Fedora
9 and loncapa 2.7.1? It seems that the pdf files do not contain any
letters - essentially blank, just lines, if there is any graphics.
The tex files have all the letters and somewhere during the
conversion progress, the letters got drop. Wonder if it is an issue
with fonts files. I have submitted a bug report.
