Added Blank Characters after Submit button in IE 7

I've been trying to style the Google_CSE block and came across a problem in Internet Explorer. I think that the problem isn't necessarily with the CSS but the form - though I could be wrong.

In Internet Explorer 7, there are blank characters after the Submit button and it's extending the width of #google-cse-searchbox-form. This problem does not occur in Firefox. I've looked in the different module files to see if the culprit is in there, but I wasn't able to find anything.

Here is the CSS in case someone wanted to look at it (we're still working on it):

/*Google custom search form */
#navbar-inner #block-google_cse-0
     {
     float: right;
     margin-right: 4px;
     margin-bottom: 0px;
     width: 315px;
     display: inline;
     }
  
#navbar-inner #block-google_cse-0 .content #google-cse-searchbox-form
     {
     float: right;
     padding-right: 0px;
     margin: 0px;
     display: inline;
     }

#navbar-inner #block-google_cse-0 h2.title
     {
     color:#000;
     font-size:.8em;
     padding: 2px 5px 0px 0px;
     } 

Any help would be wonderful! The site, unfortunately, is inaccessible to the general public. If you need further information, I will supply it.

Thanks!
