I recently upgrade to office 2013. Excel is functioning differently when trying to view two or more sheets (sheet1, sheet2, etc...) within the workbook. When I go to "New Window" it opens what appears to be a complete new stand a lone workbook with full tool bar and ribbon. When I do "Arrange All" Horizontal and active workbook It fits them as two or more workbooks each with their own full ribbon and tool bars as though they are totally different workbook. The ribbons and tool bar eat up all the screen space.
My previous version of excel once you did the "Arrange All" the sheets were stacked in the same workbook with only the one ribbon and tool bar at the top which was only interactive to the specific active cells. Do I have a setting/option turned on or off that I'm not aware of? (Also using Win 8.1 64 bit)
