How do I close a form opened with window.showModalDialog?

I've opened a form with:
      newWindow = window.showModalDialog("\\Test1.asp")
      newWindow.focus();

In Test1.asp, I have a "close" hyperlink:
      <a href=# onclick='javascript:self.close();'>close</a>

When I click on the hyperlink it opens the same form in another another browser and displays the error message:
"The webpage you are viewing is trying to close the window
Do you want to close this window?""

If I open the form with:
      newWindow = window.open("\\Test1.asp;
      newWindow.focus();

then Test1.asp closes ok.

I need to only open 1 instance of this form so how do I close a form opened with window.showModalDialog?
If it's not possible then is there a better method?

{
  var a = new Array;
  a[0] = 1;
  a[1] = 4;

  var r = window.showModalDialog('http://developer.mozilla.org/samples/domref/showModalDialogBox.html',
      a, "dialogwidth: 450; dialogheight: 300; resizable: yes");
  document.getElementById('foo').textContent = r;
  alert(r);
}
</script>

Be aware that showModalDialog only works (correctly) in IE.
Script execution within the opening window stops, so you cannot close the window from there.
You can only close the window using the close icon in the right upper corner of the dialog, or by javascript (which you already have).

The fix for your link within the dialog is simple.
Put this in the head tag of your modal
<base target="_self" />

Open in new window

I used <base target="_self" /> in the dialog form and window.returnValue to return the info to the caller before window.close();
