Some instructors have reported losing their work when editing Pages, Assignment instructions, Quizzes or other areas within Canvas while using Safari or Google Chrome and using an Apple Mouse or the trackpad. It is possible to ‘swipe’ using one, two or three fingers within the Mac operating system, and this gesture can cause the browser to ‘erase’ the work and revert back to the original page when swiping left to right.
If this situation occurs, you may wish to
a) disable Gestures under the System Preferences: Mouse or Trackpad if you do not use this feature
b) set the Gestures to be three fingers, so it is unlikely to happen by accident
b) use Firefox as your browser for Canvas, if convenient
