Pausing a Session

  You can put your current session on hold indefinitely and
  lock your workstation without ending your session.  When
  you put your session on hold, your screen is cleared but your
  session is maintained exactly as it was.  Any applications you
  started continue to run, and you can resume working without
  having to recreate your screen environment.

  To put the current session on hold, choose Pause from the

  Session Manager's Session menu.  Your screen is cleared and
  the Pause Session dialog box is displayed.

  To continue your session, type your password and press

  Return.  If you make a mistake while typing, click on the
  Clear button to cancel what you've entered so far.  Then
  retype your password correctly and press Return.
