Hi Michael,

What is the difference that the Native List control brings?

What does the Native bit mean... Native to what?

Curious as I've never really looked at these 3 objects, I've managed 
with the normal List Control, and now I'm wondering, have a missed 
something useful here.

Here I’m filling a list and I want to move the current line to the last line in the list, but I also want it to scroll down to show that line.  If the selected line is below the viewable area, it selects the line correctly, but the scroll bar is positioned at the very top of the list so you don’t see the selected line.
