Cannot get OnLButtonUp() to fire

[Demonpiggies]

I cannot get the OnLButtonUp to fire unless I've moved the mouse. It will fire after the DoubleClick event and after MouseMove event but it will fire when user clicks on an item. It seems dependent on MouseMove. why? (click down, OnLButtonDown fires, Button clicks up, nothing) Is there something I missed or need to move somewhere else? I've been stuck here for about 2 days now any help would be GREAT!!!

ASSUME: m_iOld/NewSelection is -1 by default

void CDeviceListCtrl::OnLButtonDown(UINT nFlags, CPoint point) 
{
	//Call to the base class
	CListCtrl::OnLButtonDown(nFlags, point);

	//capture mouse movements
	SetCapture();

	//Set flag to off
	m_bIsSourceSelectionDone = false;
	
	//Get position of newly selected item
	m_iNewSelection = GetSelectionMark();

	TRACE( _T("OnLButtonDown: new: %d old: %d\n" ), m_iNewSelection, m_iOldSelection );

	//Flag for the other two listeners
	m_bIsDraggingAction = true;

	//Set new item to selected
	SetItemState( m_iNewSelection, LVIS_SELECTED | LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED );

}

void CDeviceListCtrl::OnMouseMove(UINT nFlags, CPoint point) 
{
	//Call to the base class
	CListCtrl::OnMouseMove(nFlags, point);

	//Leave if not selecting a source
	if( !m_bIsDraggingAction || !(nFlags & MK_LBUTTON) )
	{
		return;
	}

	TRACE( _T("OnMouseMove: index %d old: %d\n" ), m_iNewSelection, m_iOldSelection );
	
	// Get the current mouse location and convert it to client coordinates.
	CPoint pos( ::GetMessagePos() ); 
	ScreenToClient(&pos);

	//For a basic HitTest on the item's rectangle
	CRect rectSelection;
	GetItemRect(m_iNewSelection, &rectSelection, LVIR_BOUNDS);

	//If the cursor happens to be on the newly selected button then depress it
	//else keep the old button down
	if( rectSelection.PtInRect(pos) )
	{
		SetItemState( m_iNewSelection, LVIS_SELECTED | LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED);
	}
	else if( m_iOldSelection != -1 )
	{
		SetItemState( m_iOldSelection, LVIS_SELECTED | LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED);
	}
	else
	{
		UnselectDevice();
	}
}

void CDeviceListCtrl::OnLButtonUp(UINT nFlags, CPoint point) 
{
	TRACE( _T("OnLButtonUP: index %d old: %d\n" ), m_iNewSelection, m_iOldSelection );
	if( !m_bIsDraggingAction )
	{
		return;
	}

	// Get the current mouse location and convert it to client coordinates.
	CPoint pos( ::GetMessagePos() ); 
	ScreenToClient(&pos);
	
	//For a basic HitTest on the item's rectangle
	CRect rectSelection;
	GetItemRect(m_iNewSelection, &rectSelection, LVIR_BOUNDS);

	//If the buttonUp happens on the new selected button then depress it
	//else keep the old button down
	if( rectSelection.PtInRect(pos) )
	{
		UnselectDevice();
		m_bIsSourceSelectionDone = true;
		SetItemState( m_iNewSelection, LVIS_SELECTED | LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED);
		m_iOldSelection = m_iNewSelection;
	}
	else if( m_iOldSelection != -1 )
	{
		SetItemState( m_iOldSelection, LVIS_SELECTED | LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED);
	}
	else
	{
		UnselectDevice();
	}

	m_bIsDraggingAction = false;
	m_iNewSelection = -1;

	ReleaseCapture();
	//Call to the base class
	CListCtrl::OnLButtonUp(nFlags, point);
}

Well if it matters to anyone:

  //Call to the base class
  CListCtrl::OnLButtonDown(nFlags, point);

this call actually "eats up" the OnLButtonUp messages.
Taking this call out allows mfc/vc++ to post the up event and let it be handled EVERY time.
