I'm completely new to LaTeX. I've downloaded LyX 1.6.8 which uses MiKTeX 2.9, so there is probably some markup which is not required. When I create a PDF from this a bitmap font of AMSFonts is used.
If I uncomment \usepackage{palatino}
(EDIT like it is below) the font is smooth, so I guess this has to be the problem. According to the documentation of AMSFonts the type 1 font is included. It just seems it's not used.
Thanks for your time!
