This sounded good. But.....(there's always a but): when I make a thread of
the function executed by pressing the button, it forms a thread, that is
okay. But this thread needs some input from the main application. But when
I do that, nothing happens and if the thread is closed, it complains about
async-state (doh, I changed some variables) and gives a segmentation fault.
But is there any way to "flush" these variables so that the separate thread
also regonizes these changes? That would be real threading.
