Hi Ian! The overlay did not work well for us, either. It only works to a certain point, but for instance when you size the window and use automatic scaling for the components then sooner or later it is not good enough.
We were not able to wait for the new components coming, so we did buy a SDK package from one of the vendors which already had the component (in our case we ended up with VisualBI). It solved our purpose!
Kind regards Kristin
