Thanks, Terry. I have Street Atlas installed on both a desktop and a laptop, both runniing XP. The problem I am discussing relates to the display of a route as it is being developed by adding "via's". The display show the route as a straight line between the "via's" points, disregarding the actual roads. This is unlike Streets and Trips, which I am more familiar with. Why does Street Atlas do this and is there a setting to cause the display to track the roads instead?
