listview offset   

I have a listview with large icons. When user clicks, say the top left
of an icon, and in
the mouse down event i have
Point p = listview1.PointToClient(new Point(MousePosition.X,
MousePosition.Y)),
if I then compare p to listviewitem.Position, where listviewitem is
the icon the user clicked,
then in some cases the two points aren't equal. Anyone that can
explain why this offset exists
and is there a way to know what this offset would be? i.e. is there
e.g. a property of the listview
that holds this?
