If a behavior you've added isn't working out, you can easily get rid of it or modify its settings. You do both in the Behaviors task pane.
To display a behavior, you need to select the tag or page element you first attached it to. Then you'll see all related behaviors set on that tag appear in the Behaviors task pane. To delete a behavior, right-click it, and then select Delete. Or click the action and then, at the top of the task pane, click Delete. Be careful heredon't press the Delete key. If you do, FrontPage deletes the entire element, not just the action you attached to it.
If all you need to do is make a change, it's easy to modify a behavior. To change a behavior's event, just click the event in the Behaviors task pane, and then make another selection from the drop-down menu that displays, or right-click the action and select Choose Event. To edit an action, just double-click it in the task pane and make changes in the dialog box that opens.updated
