Hey Don,
You seem to be having some difficulty with Microsoft's concept of "map" files.
Each of those files you referred to are separate "map" files. You can only have one open in Streets&Trips at a time. So you have a couple of simple options.
1. You can just open another copy of Streets&Trips with your planned route in it and open another copy of Streets&Trips and open one of those map files with the desired POI list in it. Then you just switch between them to see what you want to see ... the route or the POI/pushpin list.
To open a second copy of Streets&Trips, just launch it the way you normally would, by double-clicking the desktop icon or launching it from the Programs list in the Start menu.
Or...
2. You can combine those four POI lists into the map file with your route in it. To do this, you need to run two copies of Streets&Trips.
- In the first one, open your file with the route in it.
- In the second copy of Streets&Trips, open one of your POI files.
- Select the pushpin set and use the Copy command.
- Switch to the copy of Streets&Trips with your route in it and Paste the pushpin set.
-* Switch back to the copy with your POI list in it and open the next POI list.
-* Select the pushpin set and Copy.
-* Switch to the copy with your route and the first pushpin set and Paste the second pushpin set.
- Repeat the last three steps for the remaining two POI lists.
- Save the map file so it now contains the route and your four POI lists (pushpin sets) whenever you open it.
Now you can take another step in simplifying your use of the POI lists.
- Open the map file that has your route and your four pushpin sets in it.
- Delete the route.
- Save this new file that only contains the four pushpin sets as a Template file with a name that makes sense to you.
Now, whenever you want to start route planning and also have those pushpin sets available along with the route, just open the template file you just saved as your starting point for the planning. Make a route and save a map file with a relevant name and work with it for that trip. It will have the four pushpin sets in it and your new route, all available within the one map file.
I hope that helps.
