<< Also, after going to the document settings I'm no longer able to view the PDF output.
These "class switch errors" come back as "export errors", although they are unrelated to LaTeX. Looks like the log window isn't cleared correctly. >> Any idea as to what might be causing them? The export errors bug is fairly new. I thought that it might be specific to Mac OS X, but after updating the SVN version on my Linux box this morning, I'm getting them there as well. Before, the "Undefined" error would allow for the document to compile. That no longer works. I'll file a bug report with what information I've been able to piece together. Cheers, Rob
