So here's the scenario:

I've got 2 ListViews, one above the other.  These are
inside of a ScrollableControl.  When the 2 ListViews are
large enough, they cause the ScrollableControl to display a
vertical scrollbar.  The problem comes in when I change the
focus from one ListView to another.  I do NOT want the
scroll position to automatically adjust itself to display
the top part of the focused ListView.  I want the focus to
change, but the scroll position to remain the same.  I
can't seem to figure out how to do this, while keeping the
focus functionality the same.

For example, I can replace WM_SETFOCUS messages with a call
to Invalidate(), but this will prevent the items in the
ListView from appear focused, although I certainly could
send a message to the listview indicating to display the
item as focused, though I don't really like this way.  Any
suggestions?
