When a cross street order is defined in the streets manager, Intersection Magic assumes this is the entire list. As a result, it only shows the streets you've created in the order list.
Changes made in version 6.615 require user verification of cross-street data. Note that because the changes only affect cross street ordering associated with the use of aliases, this information only applies to users who have prepared cross street listings using the streets manager. Also, if aliases have never been used, this information does not apply.
Earlier versions of Intersection Magic have a small bug where a street is not truely deleted when using the delete feature in the Streets Manager.
