Hello, I have Microsoft Excel 2016 Installed on my Dell PC on Windows 10. I have a few .xlsb spreadsheets that are quite large that I work on almost daily. Every day at random, the window will freeze, so when I hover my cursor over a corner of the window so I can resize it, normally, the minimize, full screen, and close toolbar buttons at the top right, will resize along with the window. However, the window seems to freeze, and I can resize the window, but when I click on or in a cell, the window stays frozen. I have attached a few screenshots. I have already disabled all add-ins in case that was the issue. I have tried Quick Repair and Online Repair from Control Panel, and have rebooted my pc countless times. Any advice?
