For some reason LyX 1.5.4 no longer produces a .PDF, .PS, .DVI or LaTeX export
file of either type when requested.
Perhaps it is because of an error that I have introduced in my file, but there
is no error message when I request the output file.
Some of my short earlier .lyx files work OK, but I am now having a similar
difficulty with another .lyx file of about 45 pages that I don't think I have
changed.
Some operations have become quite slow too compared to earlier and other
applications, even when LyX is the only open application.
-- thanks in advance for any suggestions.
Why not trying Lyx 1.6?
I think Lyx 1.5.4 is outdated.
