Multiple webbrowser control parent/child pop up

[jsublime]

I'm stuck here and could really use some help.

I have webbrowser1 which has about 24 embedded links and the following html:

 launches child window pop up
        function launchFeatures(a, b, c, i, d, e, f, g)
        var m,u;
        var tn =  document.Detail.sub[i].value;
       if ( tn == null || tn == "" ) 
        url = "./feature.jsp?a=" + a + "&b=" + b + "&c=" + c + "&tn=" + tn + "&d=" + catg + "&action=" + act + "&f=" + f;
        MM_openBrWindow(u,'locked','scrollbars=1,resizable=1');     
        return true;

If I call this function it creates a popup window. I'd prefer to have the pop up display in webbrowser2. I can do this using webbrowser2.navigate(url) but it doesn't preserve the link between the parent/child windows.

The child window is therefore unable to make changes to the parent window. How can I accomplish this?

Example code from the child window:

window.opener.document.getElementById("feat" + value).value="* FEATURES"
