Sukerfish 'Drop Down Menu' problem in I.E.7

Hi,

i’m trying to get a Sukerfish drop down menu implemented on my site.
I’ve uploaded an HTML file to test the code on all browsers and I’m having the following problem in I.E 7.

The drop down menu goes to the right of the hovered element instead of below it!
It works on all other browsers except IE7.

All the CSS code is embedded in the HTML file so you can see it when you view source code.

Here’s the file:

Please help if you can
