Hi,

   I have an swing applet which has been loaded in IE using JRE1.5 plugin. Now if I click the close button in the browser, it is not closing but allows me to close after clicking the refresh button.

Any idea?

Note: The applet is been launched using some javascript. i.e., clicking a html button will launch the applet and the applet will be displayed out of the browser, ie., not embeded in the browser.

applet is launched through the below JS,

function launchApplet(appName,className){
      var c=document.getElementById("appletContainer");
      c.innerHTML="<applet>...</applet>";
      return false;
}

ya, they are implemented properly.

FYI, the same app works fine if the plugin is 1.4.2.

BTW, what makes difference here if I don't implement stop()?

strange, not sure what the problem is.
What does your applet do, any threading?

Yep, it has lot of threads.

The stop method itself is not called. The strange behaviour in browser is, when I clicked the applet launcher button, the IE icon in right top of the browser is changed to inprogress state and it never get to the original.

your stop() method should be closing any threads that have been started.

Note: As soon as click on the applet launcher button, the close button in the browser doesn't work. The application will launch threads only after the user logged in to that.

Exception in thread "Thread-15" java.lang.NullPointerException: null pData
      at sun.awt.windows.WComponentPeer._dispose(Native Method)
      at sun.awt.windows.WComponentPeer.disposeImpl(Unknown Source)

I am able to workaround this problem on my own. I have removed the javascript code and used framesets to load the applet and the IE close proble is not appearing!
