No


Operating System Configuration Information (be specific):

Linux gumnut 2.2.14-5.0 #1 Tue Mar 7 21:07:39 EST 2000 i686 unknown


Hardware Configuration Information (be specific):

IBM Thinkpad 600X standard config. 320Mb ram.


Bug Description:
---------------
open just about any Swing application, nothing appears in the window.


Steps to Reproduce (be specific):
--------------------------------
use the attached code, Frame1.java. COmpile and run it. It should show
a canvas with a red "X" and a menu. Instead nothing is shown.

Curiously, you can click where the menu should be, and, so long as you
click correctly, the menu works.

Test program:
================
//package fd;

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

//import com.esri.aims.sdk.sys.tp.ThreadDialog;
//import com.esri.aims.sdk.sys.tp.ThreadPool;
