I'm using Excel 2000 on Windows 10. No problems until today. If I choose, for example, to show the formula bar, then the worksheet tabs at the bottom of the interface are half hidden. If I then show a toolbar, the tabs are entirely hidden. Instead of reducing the number of rows visible for the spreadsheet, Excel cuts-off the lower portion of the interface. I do have the "show tabs" option checked, and I do have the window maximized. Can anyone suggest how I might fix this?
