Adding any basemap to a map document causes map zooms to be delayed UNTIL panning performed. Problem worsens with subsequent pans until even pans quit working.
Removing the basemap does NOT correct problem (and basemap remains on screen)
Starting a new map document does NOT correct the problem
All basemaps cause the problem
Redraw has no effect at all
All zooms delayed until pan...extents, zoom layer, zoom in zoom out, map scale....
Even if Basemap is the only data in the document, the problem exists
Hardware acceleration does NOT improve or worsen problem
Only way I've found to solve problem is restart ArcMap
Other mapping applications (Google maps, Caltopo, OpenStreetMap) run flawlessly

Called ESRI techspport who suggested some potential workarounds. Part of this blog: https://community.esri.com/groups/technical-support/blog/2013/04/01/having-issues-adding-arcgis-onli...
item #5 was the successful workaround. So adding a basemap via GIS server connection. Unknown why the "add basemap" approach didn't work
