I have the Notes tool and a Bible open, among other things. I selected text in the Bible and pressed Ctrl+K to highlight it. I then went to my notebook to try to find the note with the highlights. Now when I hover the mouse pointer over the notes or the scrollbar next to the notes, the list of notes scrolls. I don't have to touch anything in the notebook -- I just hover over the notes or the scrollbar by the notes.
It probably had nothing to do with pressing Ctrl+K, but that is when it started.
I could only get out of this state but restarting the program.
I will let you know if I can make it happen again.
