I am running Zone Alarm Extreme version 8.0 and Java Version 6 Update 16. After installing Internet Explorer 8 the test Java Applet in http://www.java.com/en/download/help/testvm.xml does not run. I have changed the Program Control Smart Defence from Custom to Auto. The Applet still runs in Firefox and Opera, and runs on IE8 on another PC which does not have ZA Extreme running. Any ideas?
