problem in LyX if I just use a *.sty file instead of a class. Then
LyX handles XeTeX very well. Does anyone have any theories about
what is going on? The only thing I can think of is that my layout
file is doing something to interfere with XeTeX. It compiles okay
just without the right fonts.
I have no idea what is happening, but here's how to find out.
Construct some simple test file that exhibits the behavior you
mention, i.e., it works with the sty and not with the cls. Now
export both to LaTeX. Look carefully at the preamble and in
particular at the order in which things are being loaded. Somewhere
in there is probably the difference. If not, then check the order
in which things are being loaded in your class and style files.
Maybe it's there.

So, I did what you suggested, and I am getting closer to solving the
mystery. Both preambles are pretty much the same, and it is actually
something which is present in both which causes the problem:
\usepackage[T1]{fontenc}
If I comment out the above line in the file utilizing wheaton.cls
(which basically just points to wheaton.sty), it solves the problem,
but the file using wheaton.sty directly can have the line and there
is not problem. I don't think it has anything to do with my LyX
layout file. It would seem to be related to how I have constructed
the class file or something. Is there any way to prevent LyX from
adding the line above?
Here is the class file:
\ProvidesClass{wheaton}[2009/10/04 Wheaton College Dissertation Class]
\LoadClass[letterpaper,oneside,12pt,titlepage]{memoir}
\usepackage{wheaton}
\setromanfont{Times New Roman}
\newfontfamily\hebrewfont[Script=Hebrew]{SBL Hebrew}
\newfontfamily\greekfont[Script=Greek]{SBL Greek}
\RequirePackage[babel=once,english=american]{csquotes}
If you're using the style file, does the T1 line come *before* these
fonts are set? Or still after?
Jurgen, do you have any idea here?

The T1 line is added by LyX when the *.lyx file is exported to plain
LaTeX, and there it is the second line of the file right after the
document class declaration. Moving it after the font declaration (just
before \begin{document}) does not solve the problem. There is something
about the T1 line when a *.cls file is used, as opposed to a simple
\usepackage declaration, that sets up the T1 line to trump XeTeX's use
of TrueType fonts. Is there any way in LyX to disable this T1 line? I
suppose that assumes that LyX is exporting to LaTeX before compiling.
