In addition, the ability to Create Results of the location > * Clouds, stars, atmospheric halo are map properties of each map and are stored in the .NMF rather than properties of the application > * Set Home Server restarts ArcGIS Explorer automatically
Fixes: > * Once the globe is pivoted and flying has started, the zoom in key functions correctly > * When the most recent click is on the application’s title bar or is not on the map, focus remains on the map > * Scale thresholds are honored for local shapefiles > * Add Content for KML can be added via URL > * Once added to the map, KML files are listed in the correct order in the Contents > * ArcGIS Explorer can open a .NMF file containing a globe service with group layers > * The application disables the “->” button when the “custom tasks” heading is selected > * LayerResult appears in the correct layer order > * Polyline and polygon length properties have been corrected
