In Engrave Mode I select a part then double click at the bottom of the page which brings up the copyright field.
I then change this to Revised followed by the current date.
I highlight the new text and filed and press Ctrl+C to copy it.
I then go to a different part to delete the copyright filed and past the new info.
3 times in the last week when I do this Dorico crashes. If I save after every change the program does not crash. It might be because I don’t display the field before going to a different part. Not sure.
