Double Click To Edit Copy/Paste Cell, Open Links - But Only From One Account?

Double Click To Edit Copy/Paste Cell, Open Links - But Only From One Account?

Hi there,

I have a spreadsheet. On my account, it opens links fine and copy/past fine.

However, on my team member's account, she has to double click to open links or even paste.

I think, in excel, this is called double click to edit.

How can I turn on single click?

Thanks,
Chad
