Route Overlay v Mapping

Hi - I am running Basecamp 3.1.4 with NT 2011.4 mapping from Garmin on an Imac. I am an experienced user of Basecamp and Roadtrip but am experiencing problems with computed routes not overlaying the marked roads on the screen map. All computations are correct but the coloured route line lies alongside rather than over the road on the map. This makes it very awkward to adjust routes to follow particular roads - however, it appears that if you click on a road the resultant route lies alongside it but does in fact follow the correct road. Its as if the computed route is not calibrated to the map - any ideas on how to correct the problem would be appreciated.
