Oups... sorry I did a mistake while copy/paste.
I my tes program this is really :

void CBitmapCheckBox::OnLButtonUp(UINT nFlags, CPoint point)
{
  static int c = 1;
  CString s;
  s.Format( _T("%d X OnLButtonUp\n"), c );
  wprintf(s);
  ++c;
  CButton::OnLButtonUp(nFlags, point);
}

void CBitmapCheckBox::OnLButtonDown(UINT nFlags, CPoint point)
{
  static int c = 1;
  CString s;
  s.Format( _T("%d X OnLButtonDown\n"), c );
  wprintf(s);
  ++c;
  CButton::OnLButtonDown(nFlags, point);
}

Umm... because your trace for LButtonDown says "OnLButton *** UP ***"?

I did a second test to show you the problem.

On my CBitmapCheckBox class :
------------------------------------------------------------------------------------
void CBitmapCheckBox::OnLButtonUp(UINT nFlags, CPoint point)
{
  static int c = 1;
  CString s;
  s.Format( _T("%d X OnLButtonUp\n"), c );
  wprintf(s);
  ++c;

  CButton::OnLButtonUp(nFlags, point);
}

void CBitmapCheckBox::OnLButtonDown(UINT nFlags, CPoint point)
{
  static int c = 1;
  CString s;
  s.Format( _T("%d X OnLButtonUp\n"), c );
  wprintf(s);
  ++c;

  CButton::OnLButtonDown(nFlags, point);
}
------------------------------------------------------------------------------------

After doing a double click on my button, here is what I get on my VS
console :

1 X OnLButtonDown
1 X OnLButtonUp
2 X OnLButtonUp

Why do I did not get ?

1 X OnLButtonDown
1 X OnLButtonUp
2 X OnLButtonDown
2 X OnLButtonUp
