Mouse Hover Not Working This may be a simple question, but for a long time now Safari has not registered when my mouse is hovering over something (e.g. hover over a youtube video to show the progress bar, hover over a link to highlight it, hover over the FaceBook like button to show different reactions, etc.). 

Does anyone have any insight into a solution? I've restarted multiple times since this started occuring.
I restored my Logitech settings from a backup and the problem went away.

Something must have gotten corrupted.

I have an M720 Triathlon Multi-device Mouse and a K780 Multi-device keyboard.
