By default, the BodyEventBackColor property is 0, which means it has no effect. The BodyEventBackColor property has effect only if it is set on a non-zero value, and it changes the event's body background color (BodyBackColor property) for all events that intersect with the current timer. The StatusEventBackColor property change the event's status background color.
