Getting started question on routes

[a1953mdl]

Just getting started and need some help. I use a tablet with win10. I downloaded the program, and wanted to create a route. I tried the right click and choose...... but no insert. I have a choice of select, new or delete. Select doesn't do anything visually. New gives me a waypoint in my list. But as I add waypoints, I don't get the blue line. 
I tried the control and left click but same as right click with new. 
Help please.
