Compile and run the included program. You will
notice that the scrollbar in java.awt.Choice
object fails to respond to mouse interaction
if and only if the Choice object is in a modal
dialog. Choice works fine in Frames and in
modeless dialogs.

In JDK 1.1.6 Choice works fine in all three
cases, but it fails in modal case in 1.1.7.
