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.
