[NTG-context] \setuppapersize[XY] not working properly with landscape orientation

Hello, \setuppapersize[XY] is not working properly when paper orientation is landscape. The following code results in pages of dimensions 29.5 x 29.5 cm: \setuppapersize [XY][A4,landscape] \setuppaper [nx=3,ny=1] \setuparranging [XY] \showframe \starttext second page \page last page \page first page \page content in \page the middle \page three pages \stoptext I also have an additional question: I can use \setupbackgrounds [page] [background=...] for single pages which works perfectly. But how can I place a background figure on the "whole page" (i.e. spanning across the "middle three 'conceptual' pages", which is the "second page" when printed on paper) Thank you, Mojca
