I have done some testing and the issue seems to be related to a new feature in Windows 10 called “Scroll inactive windows”. Rick’s answer: Billie, lots of folks started having trouble scrolling within open windows after installing the Windows 10 upgrade. What can I do to make it work correctly in Windows 10? Thanks in advance for your help. Scrolling worked just fine with Windows 7. Question from Billie: I upgraded my computer from Windows 7 to Windows 10 and now I’m having trouble scrolling web pages with my mouse wheel.
