You cannot edit these procedures from the Open View dialog? Or using the View Organizer? You are supposed to be able to right in the Libraries folder. If you cannot, what happens when you try?
Any files in ~/Application Support/PanoramaX/Libraries/ are opened automatically as libraries when Panorama starts up. That means that they are secret – no visible windows. I think that is why double clicking doesn’t work – the file is already open with no windows, and library files are supposed to stay secret. But the procedures and forms should be accessible at any time from the Open View dialog (make sure +Libraries is selected) and the View Organizer (make sure Include Libraries is checked).
