He folks!

I have a problem with a javascript, its a menu and it keeps getting on
the wrong place on my website!
Its really frustrating, can anyone help me?

The website it is on is:
http://www.espressogids.nl/

Problem 1: the scipt doesn't stay on one place, if you resize your
window you'll see what i mean

Problem 2: the submenu keeps getting 1 inch lower than it should :S

this is the script:
