Changing font style of graticule minute and second labels has no effect

Description

When creating a graticule with a standard label type, after clicking on Additional Properties on the Labels tab to adjust the font style of the minute and second labels, nothing appears to change.

Cause

The standard label type does not support specifying a separate font style for the graticule's minute and second values. This requires the stacked label type.

Solution or Workaround

1. From the Grids tab of the Data Frame Properties dialog, choose the graticule you wish to edit and click Properties.
2. On the Labels tab, click Additional Properties.
3. Change the label type from standard to stacked.
