are you sure?
I haven't been able to get it working, have you had any success with it?
I think the window object only really effects the frame, not what's inside the frame, hence why it says 'The transparent feature is only supported on Vista and above with DWM (Desktop Window Manager) enabled. ' as DWM deals with things like the transparency of a window's border, rather than what's inside which is determined by nw.js
