I just updated to LyX 2.0 (mac os X 10.6.8) and the pdf preview feature no longer works.
It used to pop up in adobe acrobat. Now LyX successfully processes the file, but no longer
opens the acrobat window. I am still able to successfully export a pdf to my directory
tree, but of course this requires the extra step of opening before the file is viewable.
I have tried hard-wiring the pdflatex executable to acrobat under Preferences --> File
Handling --File Format --> Viewer but to no avail.
I can open a dvi but dvipdfm doesn't work, so I suspect there's something in the link to
the pdf handler that is broken.
Thanks for advice.
