Yes, you need to call  onXXX(True)  just prior to WinMain(...) This is =
because the library now assumes that setHandler() is the normal method =
and onXXX is being phased out.

To convert this you could do  something like ...

     sequence onClick onClick =3D {} -- Overrides the global in =
win32lib.
     procedure xfr_click(integer self, integer event, sequence parms)
          call_proc(onClick[self],parms)
     end procedure

     for i =3D 1 to length(lbt) do
         if lbt[i] > length(onClick) then
            onClick &=3D repeat(-1, lbt[i] - length(onClick))
         end if
         onClick[lbt[i]] =3D routine_id(leftButtonProcess[i])
     end for
     for i =3D 1 to length(rbt) do
         if lbt[i] > length(onClick) then
            onClick &=3D repeat(-1, lbt[i] - length(onClick))
         end if
         onClick[rbt[i]] =3D routine_id(rightButtonProcess[i])
     end for
     setHandler(lbt&rbt, w32HClick, routine_id("xfr_click"))
> .
> ----------------------------------- Exit

With the new win32lib, this can be made event more simpler. You delete =
these four lines ...

 ----- Exit Button ----------
 procedure processExit()
     closeWindow(Main)
 end procedure

and on the create() for the button you add the flag value w32AUTOCLOSE =
thus...

   btnExit =3D create(Button, "E&xit", Win, l,t,w,h, w32AUTOCLOSE)

and that's it.  =20
