Hmm, well that is what I though but it really freezes up good. I changed
my way of using wx & twisted, opted into using the normal reactor and
having wx's mainloop in a seperate thread, this seams to work great on
other platforms. I still get the lockup on Mac though but I think it's
comming from my using pyserial on a bluetooth device. I have to
investigate more but it's a bit hard too as I don't know how to provoke
the lockup and I can't debug it once it does. I think it has nothing to
do with wx nor twisted though. I will test it on other mac hardware and
software asap. Thanks for your advice,
