Certain non-user triggered actor icon changes are not reflected immediately in the zoom widget
If you drag an EML dataset actor onto the canvas, it will immediately start downloading data, and the icon will reflect that it is "Busy." In a few seconds, when it is finished caching data, the icon will change to the normal, non-busy one. This change will not, however, be reflected in the zoom widget in the lower left of the window. If the zoom widget is used (clicked on), it will then be updated.
