Following program will illustrate problem that we are facing. If we call hide() and call show() to redisplay window. Window is not visible. This worked in 1.0.2
and failing in 1.1

-------------8< -------- peekaboo.java -----------------------public class public class peekaboo {

public static void main(String[] args) throws Throwable {
  Frame f = new Frame("Hello");
  f.add("Center", new Label("Here I Am!"));
  f.pack();
  while(true){
    f.show();
    Thread.sleep(1000);
    f.hide();
    Thread.sleep(1000);
  }
}

}
