chrome menu drop down centering

[lorim]

1) Script Title: Chrome Menu Bar

2) Script URL (on DD): http://www.dynamicdrive.com/style/csslibrary/item/chrome-menu-bar/

3) Describe problem: I have put the drop down on my site. I want to center the site... I did this via the body tag and a wrapper div for the whole site.

body{text-algin: center;}

#wrapper {
position: relative;
width: 940px;
margin:0 auto;
text-align: left;
}
When I do this my site centers nicely but the drop downs move way off to the right. Any thoughts on how to realign the dropdown again.
