The usual message is "The macros in this project are disabled," and the
title bar of the message box indicates the application or project involved.
In the Tools | Macro | Security dialog, select Medium for the security
level. This will allow you to have a choice of enabling or disabling macros.
Also, on the Trusted Sources tab, check the box for "Trust all installed
templates and add-ins." When you do this, all the macros in templates in
your user templates and workgroup templates folders will be trusted, as will
those in Word's Startup folder. Unfortunately, the trust does not extend to
add-ins in the Office Startup folder, so you will still get a message about
those, but you will probably have an opportunity to choose to trust the
publisher of the macros.
