MXDs crash. I am using ESRI Basemaps which take a long time to load. After the basemap loads the other feature class layers sometimes do not display. When I first open an MXD I get the notice "ArcGIS online is not connected" - is this the cause?
What is the cause of not being able to connect to ArcGIS Online? Is it our IT security blocking it? How do I determine if it is security?
