So, the problem still here. Sometimes it is working with 
hello-messages, but sometimes doesn't work.
I will try to make minimal application. But I don't know still 
what it must do. Trying to minimize the main thread to starter of 
the second thread shows that the problems goes away..
So it will really not easy, but I will try...
Thank you.
