    If you have thoroughly looked at my code, you should have noticed the
    main vulnerability:
    a=window.open("view-source:javascript:location='http://www.yahoo.com';"
    AFAIK Securexpert's code has nothing like that and it works on Internet
    Explorer.

    You may find Netscape's opinion at:

    Could you post a publication and WORKING example of the modification, so
    we can see the difference between my exploit and Securexpert's?

    Why do you mention Java at all? My exploit does not use Java at all, so
    it should be different. Hope you make difference between Java and
    JavaScript.

    I can't understand why do you write about Java at all, it has nothing to
    do with my exploit.
