when i try to add many of the featured arcgis online layers (serviced by ESRI), nothing happens. i have success about 5% of the time. why is this not working?
Do you have any more details? Have you tried running a web debugger like Fiddler to see if there are any communication errors (Fiddler free web debugging proxy) or any errors in the browsers' dev tools/console (Chrome DevTools Overview - Google Chrome )?
