Just curious if others have noticed this bug or not.
To reproduce, build a route that includes a freeway. Add a pushpin to a location on the freeway and do a "Route - Add As Stop". On most freeways, 9 times out of 10, it will make some bizarro offroute loop. To see what I am talking about, see this series:
http://ridetoeat.com/st2010_test0.est (plain route, with 1 routestop added, and a pushpin.)
http://ridetoeat.com/st2010_test1.est (turned that pushpin into a route stop, and see what happened!)
These are all 2010, but the problem also appears in 2007 and even before that. I assume it is in '08 and '09 but I don't have them.
The problem only happens on freeways. On other roads it works fine. It doesn't happen on all freeways, just most.
If the pushpin is positioned exactly on top of a freeway exit dot, the problem does not happen.
I have reported it to Microsoft. I sent them the file and they confirmed the symptom and said they would get back with me.
