title: C# ListView with CheckBoxes, automatic checkbox checked when multi select rows
body: <p>I'm using a ListView control with multirow and fullrow select on.  When I'm selecting multiple rows at once, some of my rows magically become checked.  This happens when dragging the mouse over and also when selecting one, and shift clicking another.</p>

  <p>What in the grapefruit is going on?  Anyone?</p>
