Found part of the culprit, but can't figure out the solution. in 'fume-rescan-buffer', working modes don't flag the error caught by the condition-case, i.e. (setq fnam (condition-case () (funcall find buffer-to-scan) (error ; reached every time with LaTeX's find routine, ; not reached with C, or Makefile, etc... (the comments were added by me). So there is something in fume-find-next-latex-section-name which is throwing the error. It might be occurring in the code after the initial let* statement (which extracts the correct function name), but I don't have time (until tommorow) to figure out where the rest of the bug is, or what the solution will be. And, it might not (be occurring then). Sigh... best, -tony
