Slide Scrolling

Hi Daniel

Thank you for your question and welcome to the forum.

You can fix this by adjusting the zoom. If the zoom is set so you can see the edges of the slide in the area where the slide is displayed on your screen, then scrolling down will result in PowerPoint jumping to the next slide.

If the zoom is set so that you can't see all edges of the slide then scrolling down will result in scrolling down on just the slide you see on your screen, i.e. you will not be able to jump to the next slide.

I hope this helps.
