Sun's JVM is over at http://java.com/en/download/manual.jsp
Microsoft may or may not offer such.
I am running Windows XP with internet explorer 6.0. I checked to see that java is enabled in the browser options, and I set the cookie setting to allow all cookies. I also downloaded the newest explorer update to see if it would reinstall any necessary java plugins. I still can't navigate any site that uses java. Please help!!!
