In a custom module I am using an object that works perfectly in dnn 3.3.5 but fails on page submission when run in dnn 4.5.1.  The object is common xfile by softartisan.  

Object declaration from ascx
<OBJECT id="AXFFile" classid="CLSID:230C3D02-DA27-11D2-8612-00A0C93EEA3C"
height = "200"
codebase = "/dotnetnuke/DesktopModules/printRequest/progress.htm"
Style = "HEIGHT: 200px; LEFT: 0px; TOP: 0px; WIDTH: 450px"
width="400">
<PARAM NAME="_cx...</OBJECT>
<script language="javascript">
var XFile = document.all("AXFFile").XFRequest;
XFile.TimeOut = 3600;
XFile.Server = "localhost";
XFile.ObjectName = "/dotnetnuke/default.aspx?tabid=181";
if (XFile.FormElements.Count > 1)XFile.FormElements.RemoveAll;
</script>

The javascript that opens the page that starts the object process.
window.open("/dotnetnuke/DesktopModules/printRequest/progress.htm",null,winstyle);

Code from the page that starts the process.  The object calls back to portal tab as defined above.
  <SCRIPT language="javascript">
  function callback() {
  
   document.all("AXFFileProgress").XFRequestStream =  opener.document.all("AXFFile").XFRequestStream;
   document.all("AXFFileProgress").ShowProgress();
   opener.document.all("AXFFile").Start();
   var x = opener.document.all("AXFFile").XFRequest.Response;

   opener.document.open();
   opener.document.write(x);
   window.close();
   return;
  }
  </SCRIPT>
 </HEAD>
 <BODY onload="callback();">
  <OBJECT ID="AXFFileProgress" CLASSID="CLSID:C3EAF164-E06A-11D2-B5C9-0050041B7FF6" VIEWASTEXT>
  </OBJECT>
  <SCRIPT language="VBS">
   'This will not work in Javascript
   sub AXFFileProgress_TransferComplete()
    'uncomment the next line to get a pop-up when the transfer is finished
    'MsgBox "Transfer completed"
   end sub
  </SCRIPT>
 </BODY>

Once this is called the links on the page and the menu are no longer functional and will produce "WebForm_PostBackOptions is undefined" errors.  I have found threads on this error but most refer to .axd fixes, none of which solve the problem.  I've tried everything suggestion in related threads - turn off compression, comment it out of the web.config, whitespace, clear cache, clear browser cache, exclude webresource.axd, etc.I have spent many many hours on this so any assistance....
