This would not be so bad, except that whenever any mathematics in a file fails to latex-preview on-screen, selecting view -> pdflatex gives an error ("File error. Couldn't open file. It may be corrupt or a file format Preview does not recognize") and selecting file -> print also gives an error ("Unable to print. Check that your parameters are correct.").
Around the time that this behavior began, I remember that I had downloaded (using a link on Ronald Florence's HOWTO LyX/Mac site) MacDviX, hoping to use it for reverse dvi searches. But I never got around to installing it. Could this have caused the problem?
Any suggestions? Do I need to reinstall something? As a mathematician, if I can't preview and print files containing mathematics, then I have a little problem.
what happens, when you disable the instant preview? do you have the right converter in preferences->converter installed? (lyxpreview2bitmap)
