One of the resulting actions used in the macro options property of the current DiaryGridLine includes a font change, but the font specified is not installed on the PC from which you are viewing the current script.
The requested font change will not happen if you generate this diary without addressing this issue, and during diary generation you will receive a corresponding run-time message for every attempt made to change to this un-installed font.
Solution:
•Fix the Macro Options (recommended): Opens the macro options dialog so you can select another font.
