I have been using LyX with no problems for years, but now suddenly . . .
A paper is already 40 pages long, and has about 90 labels, with many cross-references. Just today, when I look at a PDF output, the cross-references are gone, only ?? shows in the PDF, for each cross-reference. This is about internal cross-references, not bibliographic references. All the labels and cross-references do show up okay in the paper and in the left window. Any suggestions? Mark Mandelkern
