OK, I'll try the MEP, but I'm loading each mod while carefully watching your mod list - but maybe I goofed somewhere.
Just loaded the NewUIs by TheDarkWraith and I'm getting this group of four boxed, two long blank rectangles over two superimposed squares in the middle of the screen - one labeled OK.
As I said off to try the MEP method, still getting used to this system - and that is before I even try to leave port.
