I'm sorry to hear your problems but relieved it's not just me! Did you begin to experience these problems recently or has it been longer term? Are you running the latest versions/patches of W10 and Word? Are you logged into OneDrive? Do you get this just
from USB or does it happen on your C: drive, network drive, etc.? Is it particular users or just yourself?
It's a nasty little gremlin that has the potential for massive impact. Not saving when one clicks on the save button is just a danger that really shouldn't happen - in my experience (35 years IT, 13 in an academic environment) this has never happened before
in any operating system or package that I've worked with. We have vocational students as well as academics, teenagers to 70+ year-olds, full-timers, part-timers, etc. spread over 3 universities so there's a wide spread of IT experience and even if we could
contact them, what could we say? "Save your work regularly but don't rely on clicking on the save button because it doesn't always work"?
We can't even rely on the PDF option that you suggested. By definition, our users have very complicated documents - dissertations that contain tables, figures, questions, format changes, heavy use of Styles, captions, cross referencing, academic referencing
add-ins and more - and opening these using Word reads some of the complicated stuff in as diagrams and loses some of the embedded navigation referencing. We can really only rely on PDFs for the users to be able to copy the raw text they've typed back into
the document that was supposed to have saved when they clicked on the save button (better than nothing, but a solution to a problem that just shouldn't exist).
We're just hoping that installing the latest image that contains all safe updates and patches resolves the problem. I'll keep you posted if we get any progress, in the meantime good luck!
