You will need to add a css property to your top menu to make it display over the menu writer menu. Please look for the line on your page that reads:
<div style="background-image:url(qmimages/center_tile.gif)">
and then change it to:
<div style="background-image:url(qmimages/center_tile.gif); position:relative;
z-index:1000;">
Let me know if you have any other questions.
