I have just upgraded my computer to Office 2013. Whenever I go open an Excel 2013 document, I find that the header bar (the bar with A - whatever) is being hidden by the formula bar. I've tried hiding the formula bar but then the worksheet itself just seems to move upwards so that the header bar is then hidden by the tabs at the top. I've also tried using the zoom function thinking maybe it was that but it is not. The only other option I could think of was that the workbook was in "maximized" mode but I can't find the button to minimize the internal window.
On top of that, I have discovered that when I open a new Excel 2013 document, the header bar appear. However if I switch into an Excel document that does not have the header bar, then the newly created document will also suddenly hide the header bar as well. This is driving me bonkers!
I'm attaching a screenshot of the problem. Does anyone know what is going on, and how I can fix it? I did not have this problem with Excel 2010.
