Hmmm....that's odd.
I am a big fan of Firefox browser (I am using it now), which you can get here:
http://en.www.mozilla.com/en/firefox/
It should allow JavaScript automatically. Plus it is dead easy to toggle off and on.
Tools | Options | Content | Enable JavaScript
And Java is similar
Tools | Options | Content | Enable Java
If Firefox doesn't work for you, then I suspect you've got an issue with your security software (Norton or whatever you are using).
Hope this helps.
Best regards,
Kevin
