[NTG-context] \showlayout values

Dear list, I have the following sample: \setuplayout[backspace=2.5cm, cutspace=2.5\backspace, rightmargin=1.75\leftmarginwidth, width=middle] \showframe \starttext \showlayout \stoptext Values equal to 0pt are written as 0ptpt. I guess this might be a typo somewhere in the code. But I would like to know the actual values of rightedge and rightedgedistance. I assume I’m missing something. But if the right margin shows its outer edge, there should be a measure that shows the distance between the right margin edge and the right paper rim. Or shouldn’t it be? Many thanks for your help, Pablo -- http://www.ousia.tk
