Thanks... but I'm no big fan of vb :-(. It does work in IE, but it does 
not work in e.g. Opera. Furthermore, when I tried validating the 
result (very simple in Opera, just press A-C-v :-), I got this error:

   Line 18, column 30: required attribute "TYPE" not specified (explain...). 
    <script language='vbscript' >document.all.text.focus</script>

although it was easily fixed:
  <script language='vbscript' type='text/vbscript'>document.all.text.focus</script>

However, I did a bit of searching and found this link:
	http://javascript.about.com/library/scripts/blfirstfocus.htm

which I modified into the snippet of code that can be added anywhere after 
the form. (It works in Opera and IE, and should work in most other browsers)

<script language='javascript' type='text/javascript'>
  var TForm = document.forms[0];
  for (i=0; i<TForm.length; i++) {
    if ((TForm.elements[i].type==\"text\")||
        (TForm.elements[i].type==\"textarea\")||
        (TForm.elements[i].type.toString().charAt(0)==\"s\")) {
      document.forms[0].elements[i].focus();
      break;
    }
  }
</script>

However, if you want to save a few bytes, it's enough to put this snippet 
of code somewhere after the form-element:

  <script language='javascript' type='text/javascript'>
     document.forms[0].elements[1].focus();</script>

but note that it's hardcoded to focus on the 2nd element in the 1st form, 
and doesn't check that it's the right kind of element.
