[NTG-context] issue with doublesided

Dear list, using the doublesided alternative such as in: \setuppagenumbering[alternative=doublesided] \starttext \dorecurse{15}{\input zapf\par} \stoptext I always get a final even page, either empty or not. I don’t have access to a printer, so I have to rely on copy-shops. And sometimes I forgot that the printing should leave the final blank page. Is there any way to have doublesided pages and avoid the final blank page? Many thanks for your help, Pablo -- http://www.ousia.tk
