SUMMARY I try to add a custom thumbnail to an object, but this is not stored STEPS TO REPRODUCE 1. Right-click on a target in the star map, select 'Details' 2. Left-click in the image area where a thumbnail is shown (or not, if none exists) 3. In 'Specify image location' enter/browse the path to a thumbnail file and press 'OK' OBSERVED RESULT The new thumbnail is displayed in the details view. But if the window is closed the new thumbnail is no longer shown. EXPECTED RESULT The selected change should be permanent and the new thumbnail shown each time you select the 'Details' view of that target.
