I have recently converted to Excel 2007 -- I would like the default to be
when I open a new workbook that it defaults to a 2007 workbook(.xlsx).

I have been going into Excel Options from the circle in the top left and
then click on Advanced - then Save - Then in Save fiiles in this format I
select "Excel Workbook(.xlsx).

When I have that session of Excel open when I add a new workbook it will
default to a 2007 workbook, but once I close that session of Excel and then
start it again it goes back to 2003.

Is there any way to keep the default to 2007????

Thanks.
