Re: LyX/Mac-1.3.5 -- reverse DVI search?

[Ronald Florence]

The source code for late versions of LyX/Mac-1.3.3 and for 1.3.4 was 
patched to allow reverse DVI search with MacDviX or recent versions of 
xdvi.  LyX/Mac-1.3.5 needs the same patch (included below) for reverse 
DVI search to work.

Regards,
