[Plugin: WordCamp Lisboa Ribbon] FIrefox bug

A user just noticed a bug on Firefox with your WordCamp Lisboa 2012 plugin when your mouse is over the banner, it flickers (going from cursor:pointer to normal cursor)

This is the html structure of the banner :

<a class="wclx-ribbon" href="http://2012.lisboa.wordcamp.org" target="_blank">
	<img class="wclx-ribbon-image wclx-ribbon-image-left" style="top: 0px;" alt="WordCamp Lisboa 2012" src="http://www.wysija.com/wp-content/plugins/wordcamp-lisbon-ribbon/images/wclx-ribbon-bright-left.png">
</a>

Right now, the <img> tag is the one being positionned (fixed, top 0, left 0). It should be the container (<a>) instead.
the <a> tag should also have a higher z-index than the <img> tag.

Your styles should look like this :

a {
   position: fixed;
   left: 0;
   top: 0;
   z-index: 23456; /* higher z-index than img */
   margin:0;
   padding:0;
}

img {
   margin: 0;
   padding:0;
   z-index: 12345;
}

Jonathan @ Wysija should get the credit for sugesting the code.
