If your project contains more than one definition for the same bar style,
an individual task's bar cannot be formatted using the
Bar command on the
Format menu. However, you can double-click the bar for that task in the Gantt Chart to format the bar.
When two styles are displayed for the same bar, the second defined style is
displayed on top of the first. Using the Bar command changes an individual
task's first bar style, whereas double-clicking the bar for that task in
the Gantt Chart forces the bar on top to be formatted.
