Open one instance of class browser with library A.
Open another instance of class browser with library B.
Arrange class browser windows so you can see both.
Hold down CTL key and drag Listbox class name from
from the A classes list to the B classes list.

(NOTE: Holding down CTL = Copy, no CTL = Move.)

-m.
