The strange thing is, that the locator seems to work - I find places only available in ArcGIS-online. And I can choose my locator when clicking in the dropdown-list in the Find-tool. But if I try to open and remove/activate the locator in the preferences dialog (as described in the qouted text), ArcGIS explorer imidiatly crashes.
The zoom to-error comes both from a local .loc-file and from the same locator published to a public ArcGISserver.
I will try your loc-file tomorrow.
Thanks for quick reply.
