By default this property is true and a layout may be synchronously loaded using the LoadLayout(String) overloads. This property will be set to false when an operation is in progress that would conflict with the loading of a layout such as during the drag of a pane. In such a case, one may either wait and check this property at a later time or use one of the overloads of LoadLayout(String,Boolean) that take a boolean allowing the layout to be loaded automatically after the blocking operation is completed.
