According to your route, I have been to the excel trust center. but I failed
to find the place to set the trusted locations. Is it set up in "Trust center
Setup"?

Besides, I find that Excel 2007 has a new file type which uses a new file
extention name as xlsm. what it that ?

I have added a Macro in my workbook, which is edited in Excel 2007, without
any digit certificates. I close it and reopen it, it should have shown me
a
running macro warning. but it doesn't. why?
