When the biblatex styles creates some op. cit, ibid., etc. it needs a new latex run ro get the cross-references right. LyX does not understand that. Maybe in the 2.0 version it is fixed, but I don't know. The only workaround is to export your article when finished and run it through latex and bibtex the appropriate number of times to produce a pdf. Cheers, Charles
