When objects are placed on top of text box containing text, then you can control text run around these objects. By default text boxes and picture boxes have the runaround option ON. That is, these objects when placed on top of text box with text will lead to text getting repelled from these objects unless you choose Run Around menu option from the Format dialog and un-check the Run Around check box. Whereas for graphic boxes and lines, run around option is OFF. Besides these default values, you can specify the distance that text will flow away from the object.
