[OS X TeX] Font cache problems with XeLaTeX under Snow Leopard

[J. McKenzie Alexander]

Hello there,

After upgrading to Snow Leopard, I'm encountering what appear to be  
problems with the Mac OS X font cache. At least I think that's what  
the problem is, since I've never seen this behaviour before.

Consider the following minimal sample file, which must be run through  
XeLaTeX:

	\documentclass[11pt,a4paper]{article}
	\usepackage[]{fontspec}
	\defaultfontfeatures{Mapping=tex-text}
	\setmainfont{Book Antiqua}

	\begin{document}
	This should appear in normal size.

	{\fontspec[SizeFeatures={Size={32}}]{Book Antiqua}{This should be  
big.}}
	\end{document}

When I run that through XeLaTeX, the line which says "This should be  
big." appears at the same size as the previous line.  However, if I  
edit the \fontspec command so that it says

	{\fontspec[SizeFeatures={Size={32}}]{Garamond}{This should be big.}}

instead, the second line appears big, as it should.

I think this has to do with a corrupted font cache because I *was*  
actually getting the right output earlier today, but then all of a  
sudden it stopped working. In addition, aside from the size change not  
occurring, the \emph and \textbf commands stopped working for some  
fonts.

Any suggestions on how to solve this problem would be most appreciated!

Cheers,

Jason
