It works for me here in Excel 2007. What do you have your default file type set up as, 2007 or 2003 format? (Mine is set to 97/2003 compatibility mode)

oExcel = createobject("excel.application")
oExcel.Workbooks.Add
oExcel.Cells(1,1).Value = "foo"
oExcel.APPLICATION.ActiveWorkbook.SAVE
oExcel.Visible = .t.
