Win32Lib: child window demo anomaly?

This is not terribly important, but while looking at child windows
in the Win32Lib demos, I noticed a behavior that looks bad:

"child4.exw" makes a parent & a child window, with child just below titlebar
of parent & filling parent; the parent has a button which is initially hidden
by the child window.

If, and only before you MOVE the child, you move mouse to approx. where button
is under child & click, THE BUTTON IS *DRAWN* ONTO THE CHILD WINDOW!

(Moving the child around so that new "button" is off the parent will "erase"
those portions of it from the child.)

This can't be good??

Here's the demo's code:

--  code generated by Win32Lib IDE v0.17.0
include Win32Lib.ew
without warning

----------------------------------------------------------------------------
----
--  Window Window1
constant Window1 = createEx( Window, "Window1", 0, Default, Default, 400,
300, 0, 0 )
constant PushButton2 = createEx( Button, "PushButton2", Window1, 24, 28,
260, 104, 0, 0 )
---------------------------------------------------------
----------------------------------------------------------------------------
----
--  Window Window2
constant Window2 = createEx( Window, "Window 2", Window1, Default, Default,
400, 300, or_all({WS_CHILD}), 0)
---------------------------------------------------------
----------------------------------------------------------------------------
----
procedure Window1_onOpen (integer self, integer event, sequence params)--params
is ()
 openWindow(Window2,Normal) 
end procedure
setHandler( Window1, w32HOpen, routine_id("Window1_onOpen"))


WinMain( Window1,Normal )
