Dondi: If there is any heavyweight object "in the way", you won't see the drop down. For example, if the drop down window would "touch" a heavyweight item somewhere else, it will get clipped. The white-paper on heavyweight v. lightweight on the Javasoft site covers this (see reference in the hintsandtips.txt file). -Rich Dondi wrote: > > I am also having trouble with JComboBox not dropping down.
