Hello, Including a .pdf file with \includegraphics and with a relative pathname like
\includegraphics{../path/to/file/starting/from/parent/directory/some_file.pdf} results in a "file not found" error from the pdftex.def package. When exporting as .tex and processing with e.g. TeXShop there is no problem. This problem occurs with LyX 2.0.1 under OS X; (not with LyX 2.0.0) Regards, P. De Visschere
