I have this code:
    <ul id="bar1" class="menubar">
        <li>
            <a href="#"> label1</a>
            <ul>
                <li>
                    <a href="link1.1"> label1.1</a>
                    <ul>
                        <li>
                            <a href="link1.1.1"> label1.1.1</a>
                        </li>
                    </ul>
                </li>
                <li>
                    <a href="link1.2"> label1.2</a>
                </li>
            </ul>
        </li>
        <li>
            <a href="link2"> label2</a>
            <ul>
                <li>
                    <a href="link2.1"> label2.1</a>
                </li>
                <li>
                    <a href="link2.2"> label2.2</a>
                </li>
            </ul>
        </li>
    </ul>
$(function () {
    $("#bar1").menubar();
});
To reproduce the bug (i am only interested about the action with arrow keys):
• Only use arrow keys
• Press tab
• Press right key
• Press down key
• Press left key
You will see the key response broken at this point.
If i change the order of menu all works well, so the problem is the submenu.
Also broken, if both buttons have submenus.
I seriously think it's a bug. If someone can fix should send to the authors, and merge with trunk.
