Hi,
It appears that right-clicking on a filename and trying to “Duplicate” the file from the popup menu freezes Scrivener. After a restart, the duplicate file is found in the Recovered Files folder. This has been repeated several times on my machine. I also noticed that in the main, top-of-screen menu there are two choices for Duplicate, and only one when you right click on the Binder. Could this be a clue?
