      Description

      Problem
      -------
      Java Plug-In 1.2.2/1.3 does not work under Netscape 4.6;4.7/Win 95;Win NT
      with percentage values set for the WIDTH & HEIGHT parameters of the
      APPLET HTML tag.
      This feature is part of the HTML 4.0 spec and works perfectly with the above
      on a solaris/sparc platform.
      It also works correctly with Internet Explorer 5.0 on Win 32 Platform.
      The effect is that if the browser window is resized to a smaller value
      the applet will not resize correctly but clip. This is very undesireable
      behaviour.

              JPanel p = new JPanel();
              p.setLayout(new GridLayout(2, 2));
              p.add(new JButton("Box1"));
              p.add(new JButton("Box2"));
      p.add(new JButton("Box3"));
              p.add(new JButton("Box4"));
              Container content = getContentPane();
              
              content.add(p);

            }

        }

      To Reproduce
      ------------
      1. Compile the above java code SimpleApplet.java using jdk1.2.2
         ie javac SimpleApplet.java

      2. Install netscape 4.7 and java_plugin 1.3 on pc running nt.

      3. Point netscape browser at file test1.html.

      4. The image will be displayed occuping 50% of browser window.

      5. Resize browser window to half its original width. The underlying image
         will not scale but will be clipped.

      6. Repeat the same test using Internet Explorer 5.0. It will resize
         the image correctly and it will not be clipped.

      7. Repeat the above tests on sparc solaris + netscape. The resize
         will also work correctly
