SSV dialog problems when there are multiple applets on a page.

http://java.sun.com/javase/6/webnotes/6u10/plugin2/version-selection/ explains
how to run applets with specific, old jre by java_parameter in applet tag or classid attribute
in object tag.

If a web page has multiple applets, whether it has frames or not, ssv dialog is shown
for each applet, but sometimes dialogs disappears while user press OK button on the
dialog. As a result, some applets are run on specified, old jre, but others are run
on installed jre6. Once this happens, visiting the same page would result in
running the applets on the installed jerk. Even worse, sometimes IE focus got wrong
and user may not be able to perform any action on the browser other than killing it.
