      Java(TM) Plug-in: Version 1.2.2.p001
      Using JRE version 1.2.2

      I also tested it in 1.3rc1, same problem.

      Three files are attached: start.html, JSObjectTest.html, JSObjectApplet.java.
      1. Copy these three files in one directory, here assume: c:\temp
      2. Compile JSObjectApplet.java and generate JSObjectApplet.class in the same
      directory, c:\temp. Please make sure that netscape.javascript.JSObject and
      netscape.javascript.JSException are in the classpath for compilation.
      3. Make sure all Internet Explorers (4.0 or 5.0) are closed.
      4. Make sure java plugin 1.2.2 or 1.3rc1 is installed.
      5. Open Java Plug-in Control Panel and enable "Show Java Console".
      6. Open an Internet Explorer and change the url address to be
      "file:///c:/temp/start.html".
      7. Click the link "Open a new window with a JApplet calling JSObject.getWindow
      ()". A new IE window will be created with the address:
      "file:///c:/temp/JSObjectTest.html".
      8. The JApplet will be loaded and standard output can be found in the Java
      Console.
      9. Close the newly opened window containing the JApplet.
      10. Repeat step 7, open another IE window by clicking the link "Open a new
      window with a JApplet calling JSObject.getWindow()".
      11. The JApplet can not be loaded. From the standard output, it can be seen
      that it hangs at "JSObject.getWindow()".
