One of my site members noticed that the keyboard focus is not set to the keywords field when search.php is selected, requiring a second click. I confirmed this using IE and Firefox on Vista.

Adding a little bit of JavaScript to the search_body.html worked for Firefox:

<script type="text/javascript" language="javascript">document.getElementById("keywords").focus();</script>

Unfortunately it did not work for IE. The login also has the same problem, i.e., a second click is required.
