I am adding a tray icon to the system tray from an applet. It works fine. But the following behaviors seem to be a bug:

On IE 6:
-----
When I press the back button (or enter a different URL), applet gets destroyed and the frames created by the applet are disposed. But the tray icon still remains in the system tray and not getting removed. Also the tray icon is inactive and not usable. It gets removed only when closing the browser.

On Netscape 7
-------------
The tray icon remains there on the system tray for ever and never gets removed even when closing the browser.

This is reproduced on WinXP with Mustang-b73. This must be fixed for RC.

To reproduce the bug, run the attached test on the browser (SystemTrayAppletTest.html). Check whether tray icon is added to the system tray. Click the back button or enter a different URL in the browser (or even close the browser in case of NS7). If the tray icon is not removed, the bug is reproduced.
