Hans, I’m afraid that I have another sample: \setupbodyfont[dejavu] \setuplinenumbering[style=\tfxx] \starttext \startlinenumbering \input zapf \stoplinenumbering \stoptext It compiles fine with beta from 2015.03.25 22:13. With beta from 2015.04.15 01:44, \setuplinenumbering avoids numbering the first line. If \setuplinenumbering is invoked, \setupbodyfont adds a 1 at the beginning of the first line. I’m afraid this may be a bug. Many thanks for your help, Pablo -- http://www.ousia.tk
