I have not seen any further response to my problem. The initial response I got fixed ONLY part of my problem. Apparently, no one has any further suggestions. I firmly believe that the issue is either an update that Adobe made to their software or an update to Windows 10 which Microsoft made. Maybe, just maybe, when further updates are available from either or both Adobe and Microsoft, the problem will be resolved. The most puzzling thing is that this problem didn't exist a few months ago. I know Adobe and Microsoft made available updates. I may be totally wrong but I believe some update caused my problem -- my "vote" is the culprit is an update to Windows 10 from Microsoft.
