How do I delete defunct "Shared Locations" from the Insert>Image>Resource Manager>Select Image File dialog? Also, I know that shared locations become invalid whenever the project or image directory gets relocated, but I swear I've seen it "just happen" for no apparent reason, no reason apparent to me anyway.
Right click on the shared location and choose Remove Shared Location.
Wait, you'll need to go to the Resource Manager pod. Then you can right click and remove.
Thanks, that worked.
