Comment(by hubu):

 In MapGuideViewerAPI.js, there is a function GetFusionWidget(). The
 function is defined like this:
 function GetFusionWindow() {
     var curWindow = window;
     while (!curWindow.Fusion) {
         if (curWindow.parent && curWindow != curWindow.parent) {
             curWindow = curWindow.parent;
         } else if(curWindow.opener) {
             curWindow = curWindow.opener;
         } else {
             alert('Could not find Fusion instance');
             break;
         }
     }
     return curWindow;
 }

 I think this function is already correct, no need to change it.

 After search on the whole source tree, I didn't find any other place need
 change as well.
