how to close the "Floating Menu Script"

[milius.net]

hello,

I'm using this script named "Floating Menu Script" (http://www.dynamicdrive.com/dynamici...staticmenu.htm) - does anyone know how to change the code so one can close the floating layer with a click of a mouse?

    <td width="75%" bgcolor="#FFFFCC">
      <p align="center"><b><font size="4">Menu</font></b></p></td>
    <td onclick="document.getElementById('divStayTopLeft').style.display = 'none';" style="background-color:#ffffcc;text-align:right;">
      <b><font size="4">x</font></b></td>
