stop select fields showing through div

[digiti0]

When I position a div so that it partially covers another div, any <select> fields that are on the div underneath show through the one on top. Is there any way to prevent this besides setting the visibility of the div underneath to "hidden"? I want some of the bottom div to remain visible, as if the top div were a popup.

Thanks

thanks Vladdy

i am going to get around the bug by putting my listboxes in their own little divs and set the visibility of the listboxes to hidden when I set my "popup" to visible.
