jQuery MouseEnter Error
<p>As I am writing an plugin for websites which uses jQuery I am wondering, why some of the sites which are using the script get the error:</p>

<pre><code>Uncaught TypeError: Object #&lt;Object&gt; has no method 'mouseenter'
</code></pre>

<p>The code:</p>

<pre><code>plugin.setBehavior = function() {
    jQuery('#divname').mouseenter(function() {
        show();
    });
}
</code></pre>

<p>Are there any versions of jQuery without the mouseenter event or what could be the reason for the failure?</p>

<p>Thx</p>
