Hi Fabrice, MP is too much fun for me ;-)). I mean, this is all Greek to me. I can only report that I get an empty page with both the latest beta from 2015.02.03 23:55 and beta from 2014.11.26 21:43. Just in case it might help, Pablo

what is: input hvdm; input tex; both names are also candidates for name clashes 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 -----------------------------------------------------------------

tightfunction was redundant, use curvedfunction instead (I have been cleaning up all that code as a prelude to an updat efor the metafun manual) 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 -----------------------------------------------------------------
