CTreeCtrl right click selected item update

This one has been driving me crazy.  I want to allow a user to perform actions on objects in a CTreeCtrl.  The problem is the SelectedItem of a CTreeCtrl does not update when just the right mouse button is clicked on an item.  I need it to so the user obtains the object they right click on to bring the context menu up.  To do this in the function NM_RCLICK is mapped to I get the cursor point, then after creating the popup MapWindowPoints to the CTreeCtrl and then run HitTest to find the object that the cursor is suposedly over.  It doesn't work.  It chooses an object 5 below the one the cursor is on.  Any ideas why this is or another way to get the current highlighted object (checking for TVIS_SELECTED doesn't work.  I tried that first).  Here is my current code:
    HTREEITEM hItem;

      CPoint point;

    CMenu mnuTop;


    GetCursorPos(&point);

    mnuTop.LoadMenu(IDR_BATCHES_POPUP);

    CMenu* pPopup = mnuTop.GetSubMenu(0);
    ASSERT_VALID(pPopup);
   
    pPopup->TrackPopupMenu(TPM_LEFTBUTTON | TPM_RIGHTBUTTON |
                           TPM_LEFTALIGN, point.x, point.y, AfxGetMainWnd(), NULL);

    *pResult = 0;

      //Set item right clicked on as selected
      this->MapWindowPoints(FromHandle(m_BatchTree.m_hWnd), &point, 1);
      hItem = m_BatchTree.HitTest(point);
      if(hItem) m_BatchTree.SelectItem(hItem);

Thanks.

This is code fragment from my project, it works:

    POINT point;
    POINT pt_screen;

    if ( ! GetCursorPos(&point) )
        return;

    pt_screen = point;                      // keep screen point (we need it to show menu)
    m_tree_control.ScreenToClient(&point);  // convert to tree control coordinates

    HTREEITEM hItem = m_tree_control.HitTest(point); // what item is under this point

    if ( ! hItem )
        return;

Thanks.

I had assumed GetCursorPos() was returning client coords of the class it was called from.  It seems it returns screen coords.  Thanks.
