you can flip the orientation of a toolbar by pressing "Shift" whilst the dragged out toolbar is transparent (active) i.e. when dragging it out of the docking area, press "Shift"--this will flip it from vertical to horizontal or vice versa. Or go with rickyt suggestion... Also, if you have dragged out a toolbar, double click its frame and it will fly back to that latest positioned spot...
