Confirming Closing a Create-Send Window

  If you change the header or text of a message in a Create-
  Send window and then close the window without sending
  the message, a caution dialog box is displayed.  It asks you to
  confirm that you want to close the window.

  If you do not want the caution dialog box to appear, disable
  this option.

  Click on OK or Apply to save the profile settings.  Click on

  Cancel to leave the settings unchanged.
