Hi Daryl,
I'm not so sure that earlier versions did that either. Currently the 
sequence of events for a left double click is ...

  WM_LBUTTONDOWN
  WM_LBUTTONUP
  WM_LBUTTONDBLCLK
  WM_LBUTTONUP

Win32lib does not filter the button down event. Windows itself must be 
doing that.

What would you like to see instead? ...

  WM_LBUTTONDOWN
  WM_LBUTTONUP
  WM_LBUTTONUP
  WM_LBUTTONDOWN
  WM_LBUTTONDBLCLK

maybe?

Though to be nice and logically consistant I suppose we should be seeing 
...
  WM_LBUTTONDOWN
  WM_LBUTTONUP
  WM_LBUTTONCLK  WM_LBUTTONDOWN
  WM_LBUTTONUP
  WM_LBUTTONDBLCLK

However there is no such thing as WM_LBUTTONCLK.
