Whatever happens to be showing in my main container tends to shrink in IE7 and show up fine in Firefox. Here's an example - do a search and look at the results in IE7 and FF. There's a big white space to the left of the IE7 results.

I can't see where this is coming in, although I know that on the subcategory pages when I added a long product description the spaced disappeared and it looked just like the FF page. Any suggestions? I'd like it to stay at 100% width no matter what the content happens to be.
