On my Mac (specs below) MS Powerpoint (specs below) behaves very strange: It goes to a different page (page-up or page-down) on its own.
Even when my Mac is not connected to power source (so no static electricity), and even when I do not touch the computer in any way. And there are no bluetooth mice or other devices connected.
It does this in edit mode, and annoyingly also in presentation mode.
I have no idea if this is a powerpoint or a Mac issue. This strange behavior happens only in powerpoint. It does not happen in keynote, or other MS Office apps. I have no idea even where to look for possible causes of this problem, let alone solutions.
EDIT: Additional info after useful comments:
- Behavior happens in edit mode as well as presentation mode.
- Happens in different presentations (created in powerpoint on Mac).
- The presentations have no transitions, animations or timings.
- Behavior happens sometimes, so it is hard to check. I can go for days without problems, then all of a sudden (this afternoon) in the middle of presenting for a group, powerpoint becomes recalcitrant and randomly does autonomous page-up or page-down in the middle of my story. And a couple of hours later, no problem (different wifi-network, maybe that has something to do with it..)
What could be the cause? Where to look for source of problems or solutions to this strange (but very annoying) issue?
PS: Mac = MB Pro 2017 - without touchbar - running 10.14 Mojave (but issue was already happening in High Sierra) Powerpoint = MS Powerpoint for Mac version 16.17 (180909)
