Hi all, ppchtex is really nice. after experimenting with it i found some buglets: \starttext \setupchemical[axis=off,frame=on, option=test, size=medium, scale=medium, right=2000, left=3000, height=6000,textsize=medium]%textsize and option=test has no effect - why? \startchemical \chemical[SIX,SB135,DB246,SR6,Z,CRZ6][N,C,N,C,C,C,{\LC{\color[green]{NH}}}]%here color works \color[green]{\chemical[ADJ3,Five,SB235,DB4,Z345,SR3,CRZ3][N,C,H,H]}%color does not work here, manual says it should -why? \bottext{\offset[y=-\baselineskip]{Adenin}} \stopchemical \stoptext maybe someone can also explain how the OFF key works. the behaviour is strange in my opinion. i found nothing precise in the manual. onhttp://chneukirchen.org/blog/archive/2004/05/ppchtex.html i found following explanation: 18OFF1: do 18 small steps in direction 1 (right) but this don´t work - even with the example on the homepage. best regards Bernhard
