Problem: You have chosen a map source type like Terrain but when you zoom in or out the maps automatically switch to another theme.
Background: Not all map sources are available at all resolutions. So if the resolutions range for a map source is exceeded, TrailRunner will display the best logical match it can find. For high resolutions this is satellite and for low resolutions this is roads.
Note: TrailRunner displays a small warning at the bottom of the main window to inform you about the adaptive source change.

TrailRunner can load maps only from from a limited list of internet map services. But you can import any image by drag & drop, screenshot & paste or file-import. To find other digital map resources in your neighborhood, visit the Library or watch out the developers-blog.
To make a screen-shot and paste it into TrailRunner, do the following:
• Open the digital map service in Safari
• Press Command-Control-Shift-4, a crossmark-cursor will appear
• Select the image area you want to copy, It's now in the pasteboard
• Switch to TrailRunner and click into the main view
• Press Command-v to paste the image into the map
Now you can drag around the map to place it.
