Browser : IE

Applet lifecycle shutdown sequences is not consistent on Internet Explorer.

1) Install JRE
2) Invoke IE browser
3) Go to the following Test case
   http://j2se.east/%7Ezg131198/lifecycle_test/index.html
4) switch the pages, or even open new browser windows from menu.

Expected Behavior
-----------------
Only when all browser windows of the browser instance has been closed, "Destroy" Java dialog will popup.

Current behavior
----------------
1.) Expected Behavior is not consistent on IE browser
2.) When switched between the pages using Browsers Back/Forward button causes IE to hang
3.)Any dialogs / windows popped up in the applets destroy method are hidden in the background and are not shown to the user for his response, which could cause confusion as browser is hanging.

Note : It works fine with NS browsers
