Excel not working properly since updating to Windows 11

Santero10 

I think I have exactly the same issue.

Under windows 11, the mouse pointer in Excel occasionally does not work anywhere inside the excel sheet. Normally when you point it to an area inside the sheet the pointer turns to a cross to accept input. When it does not work, it stays as a pointer and no input is possible. When this happens, the following brings it back to life

1. click other open windows (not excel) and click back to Excel

2. move the horizontal slide bar to move the sheet horizontally

I have not tried reducing and re-opening the sheet, so can't say whether this will do it also.

I have three PCs that show this exact problem. Two were upgraded from Windows 10 (supported hardware and ungraded via the Windows upgrade channel), and the third is a new PC that came with Windows 11.

This is the list of things I tried with no result.

1. reinstalled Windows 11 (returned to Win10 and upgraded again, fresh install of Windows 11) in all three PCs

2. Online repair of Office 365

3. Uninstall and re-install of Office 365

4. Removing all Excel Addins.

I called Microsoft office help, and they remote-controlled my PC and online repaired Office 365 and tried a bunch of things with no result.

Sometimes, it is so bad and I can not work on any sheet, and almost every cell entry is frozen and needed to be brought back using the above two methods. I don't think the Microsoft help team knows what the problem is and thinks that online repair will fix it. Well, it did not and I think the problem is with Windows 11, not Excel.

I can go back to Windows 10 on two of the three PCS but the one that came with Windows 11 is stuck with this problem.

If anybody can suggest a potential fix, It would be greatly appreciated.
