Newbie problem - cannot create the simplest route

I'm a complete newbie to Garmin, I just bought my first GPS yesterday and installed basecamp on my Mac. (Although I'm new to Garmin, I am a computer programmer.) When I create a route between 2 points, something very simple, I am always routed through a third point that is miles away. To make the problem obvious, I selected 2 adjacent intersections in downtown Houston and set the profile to driving. You can see what I mean from the screenshot. Obviously I'm missing something simple but I just can't find it.

Edit for more information:
1. I reset all settings in basecamp to default and restarted basecamp.
2. Set the activity to driving
3. Selected a start point in the middle of a well established street
4. I selected 4 points a few feet apart on the same street.
5. basecamp is routing me to the highway intersection in between each point on the road, see the second screenshot

Thanks for any help,
Tom

Which map do you use?

I got the Garmin 64st so it comes with their Topo 100k maps set

The 100K topo map does not contain routing information. BaseCamp uses the basemap on the device (that is routable) to calculate a route using the nearest road on the basemap. Because the basemap has very little detail that road is quite far from the position you are trying to create a route.

With the map you have the only practical option is to set the Activity Profile to "Direct". A route will form straight lines between the points you select; it won't follow the roads.

You need a routeable map to create routes that do follow roads. Garmin has many of them, but you could also try a free, OpenStreetMap based map: http://garmin.openstreetmap.nl

Thanks, for the quick response. I've looked at so many options I had forgotten that 100k maps were not routable.
