There are alot of streets (probably built since 1990) that MapPoint does not know about. I draw the streets in and label them as best I can with the primitive drawing and labeling tools availbale in MP 2002. But, when I calculate a route to a waypoint on one of these streets, MP splashes its green line straight from the closest known street as if via helicopter. The directions are "via local streets".

The error causes the waypoint sequence to be wrong. Is there a way to fix this?

No.. You might check Streets & Trips 2003, that does routing and is cheap and is more up to data than MapPoint. Actually, some have had success pasting the data from S&T into the MapPoint folder: http://www.mp2kmag.com/articles.asp?ArticleID=84 err, actually this is for the European versions, I'm not sure if you with have the same success in North America.
