Set the ActiveControl property on your ActiveForm to the component you wish to have focus.  This would be done at design time.  If you need to change it at run time, you should publish a new method or procedure that uses the components SetFocus method (i.e.  Button1.SetFocus; ) and call the published method from a javascript.  Publishing a new method is done by having the ActiveForm's .PAS file open and selecting EDIT and Add To Interface... You can follow the HELP from there.

I tried to duplicate your problem and my first suggestion didn't work (setting ActiveControl property at design time).  However, the second suggestion did work.  I published a method FormFocus similar to

procedure TActiveForm.FormFocus;
begin
     SetFocus;
     Edit1.SetFocus;
end;

I then called this from a javascript acting on the OnLoad event like this

<script LANGUAGE="JavaScript" FOR="window" EVENT="onLoad()">
<!--
MyActiveForm.FormFocus()

//-->
    </script>

I used IE 4.01 and Delphi 3.  My OLEMISC tags on TActiveFormFactory.Create were ACTIVATEWHENVISIBLE.  One other thing to think about is that any activity after the call my change focus from where you set it.  Hope this helps!

Here it is!  The important part is the object declaration for the active form object and the javascript.  The object ID is the name you make up to label your active form. That way you can call to it in Javascript.  I labeled mine StatWeb.  "window" is the constant term for the page you are working with so that will always be the same.  Hope this helps out!
