 - When you copy or duplicate a locked object, the copy isn't locked.
 - Locking doesn't prevent changes to the stacking order. See Arranging objects.
 - You can lock panel controls:
- Objects on panel controls won't be locked unless you lock the panel control.
 - When you lock a slide control, its position and appearance can't be changed. However, you can continue to make changes in the Slide Control Setup dialog box.
 
 - When you lock a button, button bar, or popover button, you can't change its position and appearance. However, you can make changes in the Button Setup, Button Bar Setup, or Popover Button Setup dialog box.
 - Locked objects can't be set to automatically resize when the window is resized. See Setting auto-resize options for layout objects.
