I click the ‘Add grid or vector labels overlay’ button in the Layer Manager, then the ‘Add command layer’ option. A blank layer is added in the Layer Manager. I type the command, for example d.rast geology (Spearfish data), in the layer, then Enter, but the map is not displayed in the Map Display, not even by using the Display and Render buttons (the Render option is on anyway) . Where did I go wrong?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Many thanks<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>A.Clerici<o:p></o:p></span></p></div></body></html>
