Advanced Search displays wrong in IE

I'm using Jahia 5.0.1 and having issues with Advance Search displaying 
correctly in IE 6 & 7. The problem is that it seems to add a lot of 
extra space on the left side of the screen - several 100 pixels worth. 
It looks fine in Firefox 2.0 and 1.5 and Konquerer.

I have traced the problem to Dwt.js. If I rename the file the page 
renders correctly in IE. My suspicion is the Dwt.setLocation function. I 
put alerts in it and they only get called when IE tries to render the page.

You can see the site at http://homeowner.onqlegrand.com. Enter something 
in the search box at the top, click on "Advanced Search" on the 
resulting page and then everything shifts to the right (only in IE).

   1. How can I fix this so that the Advance Search page shows correctly?
   2. Is there a way to not show the Advanced Search link on the search
      results page?
