Problems advancing PowerPoint slides
I recently upgraded to a new iMac. During two Zoom meetings with 20-plus members since then, I was unable to use the arrow keys to advance my shared PowerPoint slides. Instead I had to use the ultra-sensitive touch pad atop the Magic Mouse. Curiously, the arrow keys worked for the first couple of slides last night then quit working for the rest of the meeting. I did not have this problem with my old iMac running Catalina. Anyone have a clue as to what could be happening?
This problem did not occur the night before last when our guest speaker and I practiced his presentation. Neither does it occur when I practice using my laptop and iPhone as other meeting participants.
