Empty div hover event not firing in IE

None of comments and filters stuff works for me. The div is never rendered, so no hover possible.

Ultimate solution:

.aDiv {
    background: transparent url(../images/transparent.gif) repeat;
}

With a one pixel transparent gif image. Sure it works !

I know that the question has been answered but I encountered the same problem. The empty div wouldn't fire the function. And if it had a border only the border itself would start the function. I tried lots of stuff, nothing helped. Here is my solution, it's pretty much the same only thing is that I didn't use an image. Add this to your CSS:

div {             /* write the element's name, class or id here */
background: #FFF; /* you can choose any colour you like, 1.0-fully visible */
opacity:0.0;      /* opacity setting for all browsers except IE */
filter: alpha(opacity = 0); /* opacity setting for IE, 0-transparent & 100-fully visible */
}

it will work if you set a background-color or a border ...

if you could match either of these with the existing look then you would be ok..

(a background-image seems like the most unobtrusive solution)
