Due to the amount of time spent refreshing ARCGIS.com maps out in the field; I am requesting one of the two inhancements to the Basemap features offered by ESRI
This idea has been merged with Offer a simple blank basemap option for ArcGIS Online.
1. A None : for a base map: as part of the selection process: this would select a blank screen showing only mapping layers
2. A tool to turn on or off the basemap being shown:
I am using the FLEX viewer in house and have built a NONE for base maps, it works great and allows the user to zoom in beyond the basemap graphics
