Hello, I found another funny effect. Please look at the following example: \setuplayout[header=\lineheight,headerdistance=\lineheight] \setupinterlinespace[line=18pt] \setupdelimitedtext[blockquote][style={\tfx\setupinterlinespace [line=2.8ex]}] \setupheader[style=\tfxx] % strut=yes \setupheadertexts[chapter][section] % try this % \setupheadertexts[\setups{head}] % or this \startsetups[head] \framed [width=broad,strut=yes,height=\lineheight,framecolor=red] {\getmarking[chapter]\hfill\getmarking[section]} \stopsetups \starttext \showstruts \showframe[text] \chapter{ÄÖÜy} \section{ÄÖÜy} \dorecurse{3}{% \dorecurse{3}{\input tufte \par} \startblockquote \dorecurse{3}{\input tufte \par} \stopblockquote} \stoptext Can you see the header jumping? What can one do to avoid this behavior? Greetings, Andreas
