mouseover event on <li> covered by <div>

mouseover event on <li> covered by <div>

Hello,
Here's my problem. I have a list with items, it's a <ul> containing <li> elements. These are covered by a transparent <div> (used for mousetracking and speed calculations). Now how do I get jquery to catch the onmouseover event on the list elements? The div is catching all events, so none of them are fired by the li elements. Is there a way?

I hope my question is clear, if not, just say so and I will describe in greater detail.

Thanks for any help you can give me!
