Hi Mark,

Best way I've found to generate PDF files is to use Guide's "Make
PostScript File" function in the Extras menu, then convert that to PDF.
I use GhostScript to do this, using the ps2pdf utility provided with
that package. The result is still in vector form, and therefore
compact and non-pixellated, no matter how much you zoom in. Very
spiffy indeed.

GhostScript is open-source software. I also use the associated
GhostView software, in place of Adobe Reader; I find that it's faster,
smaller, and less apt to crash.
