1. Why is the loading icon keep spinning and the map seems to be hanging?
Sometimes the map is loading too many data. Try to zoom in and out.
If the map is still not responding, refresh the browser.
2. I see a map feature (symbol) on the map, but why I cannot identify it?
If there is no detail information from a map feature other than the feature itself, that feature would not be identifiable.
After clicking the mouse left button on a feature, if the Identified Result Panel shows "No result at this location...",
it means no detail map data found, but a feature is available, at that location.
3. Why is the identify infowindow sometimes slow in my browser?
For the best performance, ESRI recommendeds that you use Mozilla Firefox 2 and higher, Google Chrome, or Internet Explorer 9 or higher for viewing web maps.
Internet Explorer 7 and 8 are supported but have performance limitations when working with web maps. If you need to use IE 7 or 8, installing Google Chrome Frame
may improve your experience. The free Chrome plug-in allows your older browser to take advantage of newer web technologies in applications such as the map viewer.
These are the tools to help you working with the map.
