IE the searchresults not go away when I click in the page

Issue Summary

Hello,

thanks for the great ajax search module :-) the search is a major value added to the page.

I have found a little issue in the IE8/7 when you type a keyword in the input field the search result is displayed, but now when i click in another part of the site the searchresult is not go away.

In FF 3.6.8 the searchrsult go away when i click another part of the site.

I have test it on the http://www.huttenbouw.nl/ site too there is the same.

sorry for my english i hope you can understand my formulation.

kind regards
drew
