I've tried all suggestions to keep my windows data from scrolling up, down and to the left, past margins, without my input. It's the same in Pages, Word, or Scribner. Same when doing NYT puzzles. When on FB, my info may scroll back to the beginning. I kept hoping updates would correct the bizarre problem. Someone suggested a software in the past for this issue. I may be willing to try now. Thanks.

Thank you. Tried all. Computer will not go into safe mode. I spent 2 days with an Apple "advisor" trying every which way to find a fix. Finally admitted nothing worked. The mouse is involved some of the time, so I will replace that.
