Thanks to Taco, Robbert and Jules for their work! I used the downtime to setup a presentation style with a progress bar in the footer. But I get the same (first page) graphics on all pages, and the footer background appears under the text area as well as under the margins. * I thought \useMPgraphics would be enough to re-calculate on every page? * How can I set a background to the footer area, but page width? * I tried \overlaywidth as well as OverlayWidth in the MP graphic – how do I get the page size?
