When running the "Clean Up Text" Word add-in
(http://gregmaxey.mvps.org/Clean_Up_Text.htm), I receive the error message
"The macro cannot be found or has been disabled because of your Macro
security settings." Changing the Macro security to "Medium" still yields the
same error.

How do I authorize this add-in to run from within Word 2003 (Office 11 on
Windows XP Pro)?

Thank you for your assistance.
