On Mac OS X LyX 1.3.7 stores its information in a new location (~/
Library/Application support/LyX/)
instead of the previous ~/.LyX folder.
The LyX Installer supplied with the binary moves the old files to the
new location.
But apparently something is going wrong, since LyX 1.3.7 does not
find the latex classes anymore.
However when running the configure tool in a terminal window
everything seems OK, although the LaTeXConfig.lyx file (kept in ~/
Library/.../doc/) does only contain ??? entries.
When installing LyX 1.3.7 from scratch (thus after first removing the
old ./LyX folder) then there is no problem: a new folder is created
in the new location (but apparently it is not used). The
LaTeXConfig.lyx file is now found in the application itself, together
with al other files. Although this is probably not as it should be,
it works.
