div:hover issue on IE10 - css

Question

I have an icon: when I click on it, an other div, which was hidden, appears just upside. But only when we hover the icon. It works perfectly on FF and Chrome, but on IE10, when you hover the div hidden, it makes it appear...
Here is the html:
<div class="enveloppe_abo" id="enveloppeabo_92">
<li class="abo">
<img src="/images/avatars/femme.gif" class="avatar_40">
</li>
<div class="bulle_abo">
<div class="avatar_abo_bulle">
<img src="/images/avatars/femme.gif" width="68" height="68">
</div>
<div class="supprabo" id="supprabo_92" alt="Remove subscription" title="Remove subscription"></div>
<div class="texte_abo_bulle">steph.toto.com
<br>
<br>Blog de blog blalala et oui de deux trois et quatre informations
<br>Encore une info et oui bien s&ucir...</div>
</div>
</div>
And the css:
.avatar_abo_bulle{
float: left;
position: relative;
height: 68px;
width: 68px;
display: block;
overflow: hidden;
-webkit-border-radius: 6px;

Any solution for this please? :-(

Answer 1

Change
.enveloppe_abo:hover .bulle_abo, .enveloppe_bulaut:hover .combulle{
To
.abo:hover + .bulle_abo, .enveloppe_bulaut:hover .combulle {
Updated jsFiddle
You were selecting the entire container, not just the image
Re-Edit
You must also add display:none to .bulle_abo to retain the same functionality. Updated jsFiddle
.bulle_abo, .combulle {
// A bunch of lines
display: none;
// A bunch more lines
}
Another Edit
To add the animation back I created a CSS3 animation along with browser prefixes. Updated jsFiddle
To call it
animation: appear .25s linear forwards;
The keyframes for it
#keyframes appear {
0% {opacity:0; transform: translateY(10px);}
100% {opacity:1; transform: translateY(0px);}
}

Answer 2

The Fiddle works. Maybe you have to add the doctype at the beginning of your code:
<!DOCTYPE html>
