I'm trying to use lyx 1.1.6fix1/pybliographer 1.0.8 on Mandrake7.2 and I have the following problem with the numbering of the citations which is not crescent within the text. Here is an example: In lyx: Title Abstract .... text.... Intro Blabla [DYR00] Results Blabla [DR00, LA00] [BibTex references] (see below) And the resulting DVI/PS: Title Abstract .... text.... Intro Blabla [2] Results] Blabla [1,3] References 1 J.P. Deng and B. Randby,,, 2 J.P. Deng, W.T. Yang and B. Randby,,, 3 A. Levy and I. Agrenat,,, What's going on ? The corresponding bibtex file: @comment{This file has been generated by Pybliographer} @Article{LA00, Author = {Levy, A. and Agranat, I.}, Title = {Zinc-mediated reductive dimerizations of telluroxanthone and selenoxanthone. {T}ellurium-selenium selectivity}, Journal = {Tetrahedron Letters}, Volume = {41}, Number = {32}, Pages = {6157-6160}, month = {5 } # aug, year = 2000, } @Article{DYR00, Author = {Deng, JP. and Yang, WT. and Ranby, B.}, Title = {Surface photografting polymerization of vinyl acetate ({VA}c), maleic anhydride, and their charge transfer complex. {I}. {VA}c(1)}, Journal = {Journal of Applied Polymer Science}, Volume = {77}, Number = {7}, Pages = {1513-1521}, Received = {O}, Cote = {744}, year = 2000, month = {15 } # aug, } @Article{DR00, Author = {Deng, JP. and Ranby, B.}, Title = {Surface photografting polymerization of vinyl acetate ({VA}c), maleic anhydride, and their charge transfer complex. {II}. {VA}c(2)}, Journal = {Journal of Applied Polymer Science}, Volume = {77}, Number = {7}, Pages = {1522-1531}, Abstract = {On the basis of our earlier work, extensive Received = {N}, year = 2000, month = {15 } # aug, }
