Thanks for your reply! I am back online, using the old computer that my husband fixed. My problem with not being able to scroll was with the touchpad rather than the mouse. I know some people manage to use the laptop with only the touchpad, but they must know something I don't know.

My husband uses a desktop computer that has Windows 10. He says Windows is discontinuing that one and replacing it with Windows 11. I assumed that that also applied to me, but he says my Chromebook has nothing to do with Windows.

My 70th birthday is next month! Maybe that is why I have lost the ability to sing and play guitar. I am making some progress with the guitar, but no luck with singing. I am amazed that I have lost these things. I would have assumed it would be like riding a bicycle, which people are not supposed to forget. I have not had any illness or injury that would explain the loss of my musical abilities.
