I don't think this is a problem of Excel !
I believe this is a problem in Windows 10, the module that is managing all the windows required to realize a function like scrolling inactive windows.
Why is it Windows 10 rather than Excel?
- This specific problem occurred with a Windows 10 update
- This specific problem disappears when you copy/rename excel.exe
- When you check Resourcemonitor you will find within one active windows very strange behaviour of the subwindows and I believe the same module that realizes scrolling of inactive window is also used to realize the different subwindows within the active
window
- Before this problem specific by Excel + another program window occurred there existed already a problem when 2 or more Excel windows are open
However there must be also some difference in the way Excel interacts with Windows 10 for this function, because also MacOS users found, while scrolling around Word was OK, scrolling around Excel was not working as it should have.
I believe there is not only 1 problem in this Windows 10 module, but rather a multitude.
When I interpret Wayne's information correct, in case of a touchbar Chrome behaves strange.
And I could add another problem (but of neglectable nature) when checking an active Word window for all its subwindows. Also there I found effects which should normally not be there.
