767 and eicas displays on F4 and F3

Hi
On page 4 PFD I have it set up for 767 with frames showing but obviusly the
black background can be seen around the frames.
I wonder if its possable to change the black backgound colour to the same as
the frames.

Also Im having trouble seperating the Engine display from the eicas frame,
unlike the new situation of other instruments moving with the frame this one
does not display correctly, in my case the engine display is too big and to
the left.

Maybe enrico has not had time to get around to this yet, or is it me.

Kind regards Nigel S.
