Sorry if this is a repeat, but I couldn't find an answer here. And sorry if the answer is completely obvious, but I do appreciate your assistance with my first QGIS map.
When I try to use composer to create a printable PDF of a map I've made, clicking 'add new map', then drawing a rectangle, the map does not show up. I can add and see a north arrow image or a scale bar, either on top of or to the side of the map rectangle. I can add and adjust a frame around my map and I can change the background color. I tried to show the grid and cannot.
I downloaded a map from www.naturalearthdata.com and composer seems to work fine for me, including moving the map, changing the scale, adding the north arrow image and the scale bar.
I'm using QGIS 1.8.0-Lisboa, with Windows 8.
