1.7.3 pickRect returning no results

If pickRect is called and the rect is contained by, or only slightly larger than, an object's collision area it works properly (it will be picked). However, if the rect is much larger than the object, even though the object IS contained by the rect it will not be returned. Heres a simple mockup situation...

Add this to the end of game.cs for testing...

//
// Code for the SelectionBox object.
//

new t2dShapeVector( SelectionBox )
{
   LineColor = "1 1 1 1";
   FillMode = false;   
   CollisionActiveSend = false;
   CollisionActiveReceive = false;
   CollisionPhysicsSend = false;
   CollisionPhysicsReceive = false;
   Visible = false;
};

SelectionBox.setPolyPrimitive(4);

function SelectionBox::setStartPoint( %this, %wpos )
{
   %this.startPoint = %wpos;
   
   %this.setSize(0,0);
   %this.setPosition(%wpos);
}

function SelectionBox::setEndPoint( %this, %wpos )
{
   %this.endPoint = %wpos;
   
   %diff = t2dVectorSub( %this.endPoint, %this.startPoint );
   
   %this.setSize( mAbs(%diff.x), mAbs(%diff.y) );   
   
   %pos = t2dVectorAdd( %this.startPoint, t2dVectorScale( %diff, 0.5 ) );
   
   %this.setPosition( %pos );
}

//
// Mouse callbacks on the sceneWindow
//

function t2dSceneWindow::onMouseDown( %this, %modifier, %worldPosition, %clicks )
{       
   SelectionBox.Visible = true;     
   SelectionBox.setStartPoint( %worldPosition );      
}

function t2dSceneWindow::onMouseDragged( %this, %modifier, %worldPosition, %clicks )
{    
   SelectionBox.setEndPoint( %worldPosition );
}

function t2dSceneWindow::onMouseUp( %this, %modifier, %worldPosition, %clicks )
{
   SelectionBox.Visible = false;
   
   SelectionSet.clear();
   
   echo( "pickingRect : " @ SelectionBox.startPoint SPC SelectionBox.endPoint );
   
   %list = $sceneGraph.pickRect( SelectionBox.startPoint, SelectionBox.endPoint );
      
   echo( "found objects: " @ getWordCount(%list) );   
}

Here's a level file with an object for picking practice...

%levelContent = new t2dSceneGraph() {
   canSaveDynamicFields = "1";
   UseLayerSorting = "1";
   layerSortMode0 = "Normal";
   layerSortMode1 = "Normal";
   layerSortMode2 = "Normal";
   layerSortMode3 = "Normal";
   layerSortMode4 = "Normal";
   layerSortMode5 = "Normal";
   layerSortMode6 = "Normal";
   layerSortMode7 = "Normal";
   layerSortMode8 = "Normal";
   layerSortMode9 = "Normal";
   layerSortMode10 = "Normal";
   layerSortMode11 = "Normal";
   layerSortMode12 = "Normal";
   layerSortMode13 = "Normal";
   layerSortMode14 = "Normal";
   layerSortMode15 = "Normal";
   layerSortMode16 = "Normal";
   layerSortMode17 = "Normal";
   layerSortMode18 = "Normal";
   layerSortMode19 = "Normal";
   layerSortMode20 = "Normal";
   layerSortMode21 = "Normal";
   layerSortMode22 = "Normal";
   layerSortMode23 = "Normal";
   layerSortMode24 = "Normal";
   layerSortMode25 = "Normal";
   layerSortMode26 = "Normal";
   layerSortMode27 = "Normal";
   layerSortMode28 = "Normal";
   layerSortMode29 = "Normal";
   layerSortMode30 = "Normal";
   layerSortMode31 = "Normal";
   DebugRendering = "0";
      cameraPosition = "0 0";
      cameraSize = "100 75";

   new t2dStaticSprite(TestObj) {
      imageMap = "moonBaseImageMap";
      frame = "0";
      canSaveDynamicFields = "1";
      Position = "3.129 -1.198";
      size = "10.750 10.250";
      CollisionPhysicsSend = "0";
      CollisionPhysicsReceive = "0";
      CollisionDetectionMode = "CIRCLE";
         mountID = "2";
   };
};

Let me know if there are any issues getting this test case to work.

What I found on my box is that if you draw a small rect that is contained by the object and release, it will be detected. If you drag a large rect, say, across most of the screen, it will find nothing.
