trouble with menu position

hi, great module. i am trying to figure out how to move the image menu to the left inside the block without moving all of the block content for the entire site.

here is the problem:
http://usfalumnims.com this site is fine when viewed in firefox. But when viewed using IE the images get clipped on the mouse over.

if i relocate the image menu my problem goes away. otherwise i have to resize all of the images.

thanks for your help.
