Hi David, i am working on the same problem with Ankush.
We tried your solution and it worked, but we have one additional problem, WebFrame::windowObjectCleared() is triggered for each frame refresh so our handler gets called each time. Before our handler is called, the frame gets destroyed and we see a segmentation fault in our handler. Can you suggest any way by which prevent calling of our handler for each frame refresh.
