A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Three years later, this is STILL an issue!
I have had this exact same problem today 5.8.20. Working on a new SurfacePro - plenty of capacity. Only one workbook open. Never had this happen before. It was just weird. I was working normally and all of a sudden, for no apparent reason, I could no longer type into any cell. Found this forum and saw that this has been a known issue for years which Microsoft has never fixed. The only thing I did prior to the glitch was install the "Wrap text" command on the quick access ribbon. Hardly something that will affect typing into a cell. I took it off the ribbon but it made no difference.
Another weird issue this week is Excel showing thin black checkered bands on my display!! ****? Sometimes sections of the file are covered by what can only be described as 'blank boxes' that obscure whatever you would normally see as you are looking at your file on the screen. Clicking anywhere on the screen causes the display to go back to normal. This is so consistent and pervasive that it happens all day long. Is anyone else seeing the same thing?
It feels like the Microsoft software has been taken over by some kind of weird AI bot that wants to send us all mad.
