Not sure when this stopped working, but I can no longer view DSS Images in SkySafari 6 Pro 6.7.2 on MacOS Big Sur. Clicking on the drop-down just does nothing now. I can find nothing in the console log messages, or the debug output from the application when running from the command line. Is this a known issue?
