Wired Mouse and Trackpad selecting everything on desktop or in applications.
My wired mouse and BT trackpad frequently start selecting everything that the pointer rolls over. Then starts selecting and copying and imitates dragging and dropping text all over the screen. Even after restarting, shutdown, resetting preferences for the mouse/trackpad only give temporary correction to the problem. When it happens, control only returns when 'Force Quit' is used because when you move the pointer to the top header of whatever application is on top the
'beachball' appears. Thanks.
