jQuery 1.4.1, Opera 10.10 and Frames

jQuery 1.4.1, Opera 10.10 and Frames

I use frames in my scripts. I use jQuery 1.4.1. It works well in Firefox, Google Chrome and IE, but it didn't work in Opera. Opera didn't display the file in the frame. When I use jQuery 1.2.3, I haven't problems. Is this a bug or error in my scripts?
Sorry for my poor English.

My script are:
index.php

            <script type="text/javascript" src="js/jquery.min.js"></script>
        </head>
        <frameset rows="100%,*" FRAMEBORDER="0">
