I implemented the Java Bean Calendar Applet found on Francois degrelle's blog (Forms : a swing calendar Java Bean - Francois Degrelle's blog).
Everything worked fine.

As i updated my Firefox to 7.0.1 and the JRE to 1.6.0_29, closing the applet is taking 7s. !!

As i surfed through the internet i found that disabling the option "Activate Java-Plug-In of next generation" in the "Java Control Panel" will fasten the closing up.

But unfortunately closing the applet is still taking a lot of time :(

Can anyone advise how to speed up closing the applet ?

Best Regards.
