Using MapPoint 2002, I'm getting an annoying difference in behaviour when it comes to specifying points on a motorway which I subsequently want to use as start/stop/end points in calculating a shortest route. The idea behind this is construction sites - where access is directly off a (normally) limited-access road.
So what I do is put a marker directly on a carriageway - this is the nearest point to the construction site that MapPoint should be able make any sense of. I zoom right in, click on one of the 2 carriageways to get a little white circle marker (same happens if I start off with a pushpin), add it to the route planner then calculate the route. The resulting route will jump straight off the motorway to a minor unconnected road if one exists close enough. In some circumstances the minor road is not even the nearest!
Having got this far, I now have a square route marker over the site. If I then drag the square route marker along the same carriageway slightly and drop it (even if it's now nearer the minor road), this triggers an immediate re-routing which then corrects the 'jumping' off the motorway.
Has anyone else noticed this? Is there any way around it, because ideally I'd like this to work correctly and automatically through a VB program for an imported set of pushpins.
Incidentally, I wouldn't want to change the preferences to avoid minor roads!
Any help would be much appreciated.
