the class InteractionDialog method show.

/**

 * of an alert/dialog box. This method will block the calling thread even if the
 * calling thread is the EDT. Notice that this method will not release the block
 * until dispose is called even if show() from another form is called!
 * <p>Modal dialogs Allow the forms "content" to "hang in mid air" this is especially useful for
 * dialogs where you would want the underlying form to "peek" from behind the
 * form.
