Fireworks 4 drop down menu positioning problem

I know it may be old fashioned, but I wrote a drop-down script for the following web page using Macromedia Fireworks 4: http://www.cornerstonesservices.com/electrical/electricalnew2.htm

The problem I have is with the space at the top. Originally, I had trouble with the menu positioning because it changed depending on screen size resolution. However, I made a change in the fw_menu.js file where it reads absolute to relative. Now the menu mapping is based relative to where the script is placed (I think). This change coupled with moving the script code to the top of the page solved the positioning problem, except it caused the large space at the top.

Now I can’t figure how to get rid of the space at the top? I do not want to put the script at the bottom of the page either in case the page has to grow. Does anybody know a good work around?
