I installed jre-6u22-windows-x64 and installed Java 6 Update 20 with no problem. However, when I go to the Java Control Panel/Advanced/Default Java For Browsers I am unable to save the Mozilla Family selection. After checking the box, applying, and clicking OK the box is unchecked when I review it again. (The IE box is checked and gray so I can't uncheck it.) While the Java extension appears in my Firefox, the Java plug-in does not likely due to the browser selection problem above. Can you help me solve this problem?
