question about classes in LyX 1.5

[Brian Kidd]

I've having difficulty getting custom classes to work on LyX 1.5 beta  
for mac intel. In particular, a custom class does not show up as an  
option within the document settings even though it appears in the TeX  
information. What's bizarre, however, is that when I click on the  
show path check box, the class does not show up. The custom class is  
in the ~/Library/Application Support/LyX-1.5/clsFiles.lst file so the  
situation is a bit puzzling. Any suggestions are appreciated.

As an aside, I've had no trouble creating new classes and adding them  
to previous versions of LyX with texhash and a reconfigure.

Thanks, -Brian
