How can I change the default font of an active(!) workBOOK?
The command "StandardFont" does not work, since it is only for new workbooks and
after restarting Excel. Changing the font of a worksheet by using
Cells.Font.Name = "Times New Roman" does not hlp either, since I use Pivot
tables, and when clicking on a number in the Pivot you get the details for this
data in a new worksheet which is using the workbooks default font.
