Looks like a bug; adding blank rows works around the problem (but looks terrible):

not a bug ... (1) the matrix is centered around the math axis and has equal height and depth so indeed in columns that will not align horizontally (2) there is no n|m key support in matrices so the n does nothing in this kind of matrix Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
