Uwe, I was able to get things working okay by installing the cancel.sty package. The reason I brought up this issue is that I expected the file to be compilable in some form before the package was installed. The code in the preamble seemed intended to allow that, but it apparently wasn't working. I couldn't create a PDF form of the document at all until I installed cancel.sty.
Thanks for the great documentation, by the way. I'm going to use this as a primary resource in a mini-course I'm teaching this summer on LyX.

The big yellow note at the beginning of the Math manual tells you this: "To export this document to PDF, PS or DVI the LaTeX-packages braket, cancel, eurosym, mhchem and was should be installed. If they are not installed the document can be export anyway but the sections where the packages are required will not appear in the output. An exeption is mhchem; if it is not installed, this file cannot be exported." If cancel is not installed, the file should be compilable, but the PDF will not have the section about canceled formulas. If you are under Windows, installing missing packages is easy: - open an Internet connection - open the LyX file and view it as PDF Alls packages needed by the LyX file will then automatically be installed from the Internet. If you are not on Windows, use the TeXLive package manager to install the packages braket, cancel, eurosym, mhchem and was (if not already installed). regards Uwe
