Thank you for the clarification. Now I understand what's going on.

I used copy/paste form the file tab to make sure that I use the correct path and avoid typos.
The path shown on the files tab is completed to an absolute path by adding the MSP folder path, but "Fix Broken File Paths" works with the exact database content. I could have noticed that: I selected an absolute path for "Replace with:" but the dialog displays it as a relative path, exactly as it will be stored in the database.
