[NTG-context] How to set \definemakeup without affect other pages?

Dear all, I use \setupbackgrounds to draw a line under header. It works fine. When I setup a cover makeup and use it, the lines under headers are gone. The "headerstate=none" causes the problem. But I don't want the lines under headers appear in cover. What should I do? Here is an example. %====================================== \setupbackgrounds [header][text] [frame=off,bottomframe=on,rulethickness=1.5pt] \definemakeup[cover] [headerstate=none, footerstate=none, pagestate=stop, doublesided=yes] \starttext \startcovermakeup \input knuth \stopcovermakeup \input knuth \stoptext %====================================== Best wishes, Wei-Wei
