I have a MacBook Pro M1 with OS Big Sur 11.4. Using Adobe InDesign 16.1, but the "Save" command is greyed out, as well as the "Revert" command. Also, it doesn't ask if I want to save changes when I go to close document as it used to do. Any thoughts? Thanks.
Thank you so much Uwe for your reply. I am very curious to try your suggestion(s) but I'm in the middle of such a huge headache of a job right now I feel nervous that I might lose any styles I've set up, etc. I know, probably silly, but once bitten . . . . However, I will make an attempt and let you know how it works out. Thanks again,
