I am trying to figure out the space to the right of the third column in this example (only seems to happen in IE). The third column is dynamically being applied the class name of 'right' via javascript. Adding overflow: hidden; to ul#ads removes the whitespace. But I am trying to figure out why its happening. The page can be found here: http://media.monster.com/mm/usen/content/temp/ads.htm Any clues would be helpful! Thanks, Dave
