Windows 10: Cursor remains a pointer in Excel on extended display

When working in Excel, the cursor remains a pointer when I drag and fill the cells, it should be a Cross/Plus icon. it does turn to a vertical line when you type. Issue started last week after the system updates were installed. it does not affect excel to function but it's just very annoying. Have tried the following but no luck:

• restarting
• Unplug cable / plug it back in
• run compatibility troubleshooting on excel
• changed scaling of display
• updated drivers for mouse and display

any ideas folks? Thanks

I think you're talking about the fill handle. You can turn it on in the Excel option window.

Click on File > Options > Advanced and make sure the box "Enable fill handle and cell drag-and-drop" is checked.

But this issue should not be only when you duplicate the screen

I was having the same issue. It turned out to be my docking station. I powered off and powered on the docking station and the issue went away.
