BindingNavigator - faint border lines

Question

Does anyone know how to get rid of the faint outline on the right-hand edge of the BindingNavigator control: image view

I have already set the BackgroundColor to transparent. And the GripStyle to ToolStripGripStyle.Hidden.

You can also see a very faint line running along the bottom edge. I would like to get rid of these lines, so the control looks like it is part of the form itself (as it should when undocked).
