Why is IE causing Horizontal scrolling on my page?

https://testbed.odysseyshipping.com/

Click on the "About Us" link at the top right. All is OK in Firefox
but in IE 7, there's a horizontal scrollbar. At least, in my browser
there is as others report it OK. When I remove the margin in the code
below it is OK. Anyone know how I can fix this bet keep the margin as
I want space between the text and borders

#aboutUs_wrapper {
margin: 2em;
padding: 0;
text-align: center;
}


Thanks,
Don
