TAdvColumnGrid issue with DisjunctRowSelect

I am using a TAdvColumnGrid in which I support the use of in-place editing in most columns. I also have enabled MouseActions.DisjunctRowSelect := True;


When the user tabs through the grid, I have two issues:
- the entire row being highlighted makes it difficult to see which cell has focus
- when the focus wraps to the next row, the prior row remains highlighted, which is a serious problem, as eventually, many rows may be highlighted.

Can either or both of these problems be eliminated?
