I wanted to highlight a PDF I am using as part of my research for a short story. I figured out how to open the PDF in the external editor to make the changes I want to make. But once I make the changes it won’t let me save any of them. Every time I hit save I get the following message. “The File may be read-only, or another user may have it open. Please save the document with a different name or in a different folder”.
Do I have to close the scrivener project file before making any changes?
