Hi all, for some weeks I need to tex formulas again and tried the way I used to do it: \placeformula $$ f(t)={1\over2\pi}\int_0^\infty e^{i(\omega t-kx)} dx $$ It didn't work anymore?!? It doesn't place a number nor does it do the spacing properly. It does work the "context" way using \placeformula \startformula f(t)={1\over2\pi}\int_0^\infty e^{i(\omega t-kx)} dx \stopformula but to be honest that's quit a lot to type. "$$" is just nice and short and all the old documents I wrote wont work anymore... I run This is pdfeTeX, Version 3.141592-1.30.4-2.2 (Web2C 7.5.5) (format=cont-en 2006. 12.4) 4 DEC 2006 21:46 ... ConTeXt ver: 2006.11.29 09:55 MK II fmt: 2006.12.4 int: english/english I would be very glad for some hints. Many thanks in advance. Hubertus
