Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Classic VM (build 1.3.1-b24, native threads, nojit)



The problem is observed in jdk1.2.2 higher version on SOLARIS 8.0
-----------------------------------------------------------------------

In case of Windows environment when more number of items are added to the List
the scroll bar appears inside the List box width. Where as in UNIX environment
when scroll bar appears it falls outside the List box width and sometimes even
over the component adjacent to it.The scroll bar width is added to the original
width of the List box.

Also when an element is added to List, say by click of a button the List height
seems to change.This causes an observable flickering problem when the elements
are added in the List. I am able to observe a perceivable difference in the
height of the List box getting decreased immedaitely when an element is added
to it. Kindly give us a solution to the above specified problem.

import java.awt.*;
import java.awt.event.*;

public class ListProb extends Dialog implements
ActionListener,KeyListener,WindowListener
{
TextField tf,tf1;

ListProb(Frame f,boolean bln)

super(f,bln);
