Hi, In MkII, linenumbering stops working if \dostartattributes with a color is used inside; for example: \setupcolors[state=start] \getparameters[test][color=red,style=] \starttext \startlinenumbering \dostartattributes{test}{style}{color} Why no number? \dostopattributes \stoplinenumbering \stoptext The output of the above does not have a line number. I have been able to reduce it to the following minimal example. \setupcolors[state=start] \starttext \startlinenumbering \faststartcolor[red] Why no number? \faststopcolor \stoplinenumbering \stoptext It works if I add any text before \faststartcolor \setupcolors[state=start] \starttext \startlinenumbering Got it now! % or \strut \faststartcolor[red] Why no number? \faststopcolor \stoplinenumbering \stoptext What is going on here? Of course, everything works correctly in MkIV. Aditya
