A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
I am having exactly the same problem on a Lenovo Carbon X1 Laptop and a Microsoft Surface 3 tablet. Scrolling of the notes in presenter view using touch screen does not work, except by using the scroll bar. One thing I notice is that when you start the presentation, scrolling of the notes works on the first slide, but as soon as you move to another slide it no longer works. Even when you go back to the first slide, it no longer works. I have tried Office Repairs and there is no difference. I have not uninstalled and reinstalled, as that is a major amount of time required (my Outlook alone has about 20 accounts that all have to be added again). I think this a bug that has been introduced in a recent update.
