CFWINDOW and a form submit not working as expected

Question

Hello, everyone.
I currently have a page that allows certain users the ability to edit content directly, without having to log on to a CMS; the user can click an edit button if they have permission which will open a CFWINDOW that contains the pre-populated form for editing.
If I open the form directly in a browser (IE7 on WinXP SP3) and click the submit button, all is well.
However, when I use the EDIT link and open the form in the CFWINDOW, clicking submit will post all form data EXCEPT the input="file"; upon submit, I get an error saying that the field for file doesn't exist.
Any idea what could be causing this?
Thanks,
^_^
PS.  If required, I can post some code; but I cannot provide a link as this is on a private internal network that the public does not have access to.

Here's the code I have, thus far.
Main webpage (this calls the CFWINDOW):
<cfoutput>
     <div class="more-info">
     [<a href="javascript:void(0);" onclick="windowModal('Edit_NU','#trim(url.thisNav)#',500,700,'Edit News & Updates - #ucase(url.thisNav)#','edit_nu.cfm?thisNav=#trim(url.thisNav)#',true)">edit</a>]
     </div>
</cfoutput>
windowModal function:
function windowModal(win_name,TID,h,w,t,f,m){
     var windowName = typeof win_name === 'undefined' ? 'CFWindowName' : win_name;
     var thisID = typeof TID === 'undefined' ? 0 : TID;
     var thisHeight = typeof h === 'undefined' ? 400 : h;
     var thisWidth = typeof w === 'undefined' ? 700 : w;
     var thisTitle = typeof t === 'undefined' ? "_" : t;
     var thisDocument = typeof f === 'undefined' ? "faq.cfm?faqID="+thisID+"" : f;
     var thisModal = typeof m === 'undefined' ? true : m;
     ColdFusion.Window.create(windowName,
          thisTitle,
          thisDocument,
          {width:thisWidth,height:thisHeight,center:true,resizable:true,modal:thisModal,draggable:thisModal});
     //ColdFusion 9 bug fix
     ob = ColdFusion.Window.getWindowObject(windowName);
    ob.center();
     ob.body.applyStyles("background-color:#fff");
     ColdFusion.Window.onHide(windowName,destroyWindow);
function destroyWindow(name){
     ColdFusion.Window.destroy(name,true);     
edit_nu.cfm
<cfset client.thisNav = trim(url.thisNav) />

     marginwidth="0" height="100%" marginheight="0" align="top" scrolling="No" frameborder="0" hspace="0" vspace="0">

</table>
</cfform>
</cfoutput>
I've got the form inside an iFrame, already.  If I open edit_nu2.cfm directly in a browser, it works with no problem.  But opening it in the JS created CFWINDOW prevents the contents of the input type="file" from being recognized.
