Workaround for isFunction change in jquery 1.3

Info:

OS: Vista
Browser: IE 8.0
Drupal: 6.16
Wysiwyg: 6.x-2.1
Ckeditor: 3.2.0.5205
IMCE Wysiwyg API bridge: 6.x-1.x-dev (2010-Mar-12)
IMCE: 6.x-2.0-beta1

Browsing in IMCE double clicking a file will open the file in a new browser window instead of passing the file url back to the WYSIWYG editor dialog.
So after two days of tracing through all of the modules both in php and in the javascript files I finally found the one element causing all of my woes.

I determined that in Internet Explorer the browser can't reference abstract functions by reference from a child window to a parent window. For some odd reason IE sees the anonymous function as an object.

All other browsers FireFox, Opera, Safari/Chrome see the function as a function and of course work as expected.

Current Code:

imce/js/imce_set_app.js

line 83
//checks if a string is a function name in the given scope. returns function reference. supports x.y.z notation.
var isFunc = function(str, scope) {
  var obj = scope || appWindow;
  var parts = str.split('.'), len = parts.length;
  for (var i = 0; i < len && (obj = obj[parts[i]]); i++);
  return i == len && $.isFunction(obj) ? obj : false;
}

Patched Code:

imce/js/imce_set_app.js

line 83:
//checks if a string is a function name in the given scope. returns function reference. supports x.y.z notation.
var isFunc = function(str, scope) {
  var obj = scope || appWindow;
  var parts = str.split('.'), len = parts.length;
  for (var i = 0; i < len && (obj = obj[parts[i]]); i++);
  return i == len && ($.isFunction(obj) || typeof(obj) == 'object') ? obj : false;
}

Now the double click, image click, and "insert file" button sends the image/file reference in IE just like all of the "good" browsers. :)
