power point presenter view scrolling from touch screen

Hi Bob

My presenter notes scroll fine when my keyboard is attached. When i detach my keyboard and use only the touch screen to scroll the scroll bar disappears and stops functioning. 

Also i use dropbox and I’m able to open powerpoint files on my galaxy tablet. When i use the scroll function on my tablet, i have no issues at all.

Thank you for providing the outcome. Can you try another replicating your concern with a different laptop or PC with the same removable keyboard just to prove if the same issue happens? The reason for this is because we want to know if your concern will happen on the same environment. If the result is different, compatibility could be the reason for this issue. You can get in touch with the device manufacturer if that would be the case. 

Update us with the status of our queries so that we can continue to assist you.

I am seeing the identical issue with PowerPoint on my SP4, though I should add that touch scrolling does not even work when the TypeCover is attached. The scroll bar merely shows up, allowing you to tap it for scrolling purposes.I can scroll the notes screen using my Surface Pen, which makes the touch screen not a total loss.

I am running PowerPoint Version 1907 (Build 11901.20176) on a Surface Pro 4 with Windows 10 - 1903 that has all cumulative updates loaded as of 2019-08-14 (KB4512508). I have also replicated the issue on my wife's Surface Pro 3, which is running the same build of PowerPoint, though it is running Windows 10 - 1803. Thus this seems to be an issue with PowerPoint Build 11901.20176. The issue did not exist before PowerPoint updated itself this month.

Hi WolfHawkeAl,

What troubleshooting steps have you done so far? I want to clarify if you have performed the troubleshooting steps suggested above? If you have updated the Office suite, you can repair, uninstall and reinstall the Office apps. 

Let us know if you  have other concerns,

Bob

Hi, Bob,

I have not performed any troubleshooting steps at this point. I do not have the two hours it takes to repair or uninstall and reinstall Office and everything else works perfectly. I can work around the issue. I was merely trying to support Peter.4 by adding some more data to the discussion. My Office installs are on the monthly update cycle, so I'm just going to hope that it gets fixed in the next install.

The key point is this: for some odd reason the notes pane on Presenter View is no longer configured for scrolling. I'm guessing there's a typo in the code somewhere. This is happening on three separate machines, one of which is running Office Pro Plus by subscription and another of which is running the Home & Personal subscription. The fact that the subscriptions are different, the Windows versions are different and the machines are different, but evidencing the same behavior suggests a systemic issue with PowerPoint build 11901.20176 rather than something that can be taken care of with the uninstall-reinstall-repair two-step (as Peter.4 evidences above). From one IT professional to another, this should be understood. Thanks for the suggestion, though.
