Hi, I also ran into a problem with placeformula and margins. The attached example runs fine with the margins. But as soon the placeformula is uncommented the left and right margins are messed up. And if not all paragraphs have at both side a marginnote is get worse. Is there a way to solve this? Thanks --------8<------------------- \starttext \inmargin{inmargin}\inothermargin{othermargin}\input tufte \inmargin{inmargin}\inothermargin{othermargin}\input tufte %\placeformula \startformula c^2 = a^2 + b^2 \stopformula \inmargin{inmargin}\inothermargin{othermargin}\input tufte \inmargin{inmargin}\inothermargin{othermargin}\input tufte \inmargin{inmargin}\inothermargin{othermargin}\input tufte \inmargin{inmargin}\inothermargin{othermargin}\input tufte \inmargin{inmargin}\inothermargin{othermargin}\input tufte \stoptext
