screen zooms in and out randomly. does it with video and maps most often.

  • We have nothing to go on... Type 'zoom' in System prefs & see what you have set in Mouse &/or Accessibility – Tetsujin Dec 30 '16 at 19:14
  • Many thanks. Didn't know I had a zoom feature with the mouse. Turned it off. – jimmyford Dec 30 '16 at 19:20
