I noticed that, but did not comment on it. In asmdebugwin.ew I made
main global, and commented out the two lines
openWindow(main, Normal)
vWinMainState = kStarted
(at the time I didn't notice the second use within CallBack())
In demo.exw I added WinMain(main, Normal) before the asm_cleanup()
call. It wasn't quite right, but fairly close (displays from line 3).

BTW, what is the sequence states for?

The problem is that the include file should have and control a window,
without interrupting the main program. Using the openWindow() procedure
works perfect when WinMain() has been called, though the .ew's window is
"immune" to events if not. The problem is that vWinMainState is set to
kNotStarted.
    A solution would be to set vWinMainState to kStarted in openWindow(),
but maybe that would interfere with the main program if it calls
WinMain()?

I don't understand the problem. Here is a couple of files that show what
I think you are trying to do, and they work fine here, so I guess I don't
really understand what you are trying to acheive.

<---File: trace.ew--->
constant TraceWin = create(Window, "Tracer", 0, 0, 0, 300, 300,0)
openWindow(TraceWin, Normal)
procedure traceEvent(integer self, integer event, sequence parms)
    if event = w32HMouse then
        setText(self, sprintf("Mouse %d", parms[1]))
    elsif event = w32HPaint then
        setText(self, sprintf("paint %d %d %d %d ", parms))
    end if
end procedure
        
setHandler(TraceWin, {w32HPaint, w32HMouse}, routine_id("traceEvent"))
<---end of file--->

<---File: test.exw--->
without warning
include win32lib.ew
include trace.ew
constant PrimeWindow = create(Window, "Prime Window", 0, 200,100, 400, 400, 0)
WinMain(PrimeWindow, Normal)    
<---end of file--->


When I run the test program, the trace window opens and receives events.

It receives events because you call WinMain(). What I meant is that the
tracer should run even when WinMain() is never called, by polling 
doEvents().
To see the problem, simply replace:

WinMain(PrimeWindow, Normal)

with:

openWindow(PrimeWindow, Normal)
while isVisible(PrimeWindow) do
    doEvents(0)
end while

None of the windows should answer to any event, because vWinMainState is
set to kNotStarted.

Hmm. My example wasn't good enough. I'll try to explain again.
This method would work perfectly when the main program uses win32lib
and calls WinMain(). But, I want it to work without the main program
using win32lib, for example with an opengl library.
    The tracer should of course run in the background, and therefore
it cannot call WinMain(). That would stop the main program. The problem
is that vWinMainState hasn't been set to kStarted if I haven't called
WinMain(), and therefore my window don't receive events. Maybe 
vWinMainState should be set to kStarted in openWindow()?
