Hi Kannan,
As you mentioned, "It seems to happen only with some documents. This particular document, which will not open is just a shot of a catalog page for some merchandise I was shopping for, and I downloaded it from the manufacturer's page."
Can you share a few sample documents or at least one using the reproducible issue on your end? Also, would you let us know the file you have downloaded from the shopping site? Is it a .pdf file or an image or other file format?

Tariq,
Very sorry for the tempest in a teacup. I did more probing, and I found
that the default app for image files was changed to Acrobat Reader - which
I am sure is NOT my doing. The two or three files I was trying to open
existed in my files in both formats - PDF and JPG - with the same filename.
The Explorer in Windows 11 does not show the extension when I am viewing
the folder contents, so I clicked on the jpg file when I was trying for the
PDF version, and it woke up the Reader.
A few other such changes have appeared in my investigation after I found
this. It seems to have happened after a Windows update.
Thank you for trying to help me.
Kannan
