I've been using Word 2019 for about three months. Suddenly, a few day ago it started having a problem saving work. Initially, it was this sequence:
1. Save my work to a local hard drive.
2. Save as my work on a flash drive.

The first worked fine. The second went into the "Not Responding" mode. I don't know if it is completing what I asked or remembering what I did. I never suggests recovering the second file.


I did not install anything new except maybe a FireFox update (they're incessant). I've been using MS Office since I had 1997-2003 on Windows XP in he 1990s. What might be wrong? I don't ever seen an error message. It just hangs and no matter how long I wait, it does not resume. Suggestions would be very appreciated. Office 2019 cost a lot to fail this badly this soon.
