Instead of using the ActiveX button (which isn't supported on Macs, BTW, if that matters), you do better to simply assign the macro to a keyboard shortcut. Better still would be to call it from Word's 'BeforeSave' and/or 'BeforePrint' events, so it runs automatically without the user having to remember to do so. See:
