A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
So found out it's Logi Options+. Someone mentioned it on Reddit, and out of frustration I gave it a try. They said to uninstall the entire application, but I don't have admin rights, so I just Ended Tasks in the Task Manager, for everything but the Logi Options+ Updater, since that requires Admin Rights. Problem went away. 😯
When I came back after my screensaver kicked in, it happened again. I checked and the other two Logi Options+ apps were open. Ended them and problem went away. Just now, screensaver kicked in, problem in Excel keeps happening after I log in. I checked and Logi Options+ Agent was the only one that came back. It also seems Logi Options+ Updater doesn't cause an issue, but the other two do.
