Unloading JVM

[Charlie Boss]

I have these params in my applet html file:
<PARAM NAME="cache_option" VALUE="Plugin">
<PARAM NAME="cache_archive" VALUE="tsapplet.jar">
So i'm caching my applet in the jvm for faster applet downloads. I have one html file with a link to the applet which opens in another window. I get a problem when i do the ff steps:
1) I click the applet link and it opens my applet html file in another window. "no problem"
2) I click close on my applet which calls a javascript window.close on the window containing my applet. "no problem"
3) I click on my applet link again (as in step 1). This time the window containing my applet freezes up. Nothing happens. "problematic"
Question: Is there a way i can unload the applet from the plugin when i destroy my applet, is there any other cleanups my applet destroy method should do so when i click on the applet link (2nd time) my window opens up the applet instead of freezing.
