No access to DOM object

With IE browser, I don’t manage to access to the DOM object in Javascript.

I use Internet Explorer 9.

When I call this from Panda :

base.appRunner.dom.window

this error appears :

File "C:\buildslave\release_rtdist_win32\build\panda3d\built_cmu\direct\p3d\JavaScript.py", line 158, in __getattr__
AttributeError: window

Is there a particular syntax to use to have access to the Javascript DOM with IE ? I want to interact between Javascript and python with IE9.
With any other browser, for example Firefox, I have no problem…

base.appRunner.dom is the window object, so base.appRunner.dom.window doesn’t make sense. I guess Firefox defines this reflexively.
