There are a lot of differences in the group policy management for Office
2007, compared to Office 2003.  In Excel 2003, I had configured the Macro
Security Level to medium here:
Computer Configuration/Administrative Templates/Microsoft Office
2003/Security Settings/Excel: Macro Security level

Now that I've been looking through the Excel 2007 configuration, I can't
find a similar setting.  What would be a similar setting in 2007 - something
that does what the setting in 2003 does?  Can anybody give me some advice
here?

Thanks!
