When I open a second spreadsheet in Excel, leaving the first spreadsheet open at full screen, the second spreadsheet "toggles" on the screen, landing slightly below the first spreadsheet. I don't like this because I can't see the bottom of the second spreadsheet without moving it higher with my cursor. I want the second spreadsheet to open full screen on top of the spreadsheet which is already open on the screen.
