Components for Delphi and C++ Builder.

Hi,
I have an annoying problem using the dropdownbox property of a DBGridEh.
I have connected a listsource to a dropdownbox of a Column and when I press the dropdown button I choose a value from that list.
The problem is that when I use the keyboard to move in the list and the mouse pointer is pointing to some other value, when I press the Enter to select the value that is highlighted by the keyboard the returned value is the value that the mouse is pointing to.
It is very annoying because the user that uses the keyboard, before pressing Enter has to move the mouse pointer away from the dropdown list.
I attach a demo where you can see the problem when select a country using the keyboard and the mouse pointer is pointing to some other country of the list.

Thanks in advance
Nicholas
