Ok, now it is all working, strangely I had to remove the .hide() after
the ->join(), and consequently I removed ->join() to because now it
becomes useless . Then I have declared the message dialog as an class
atributte and filled it in class constructor. Called show and inside the
thread code handler after the routines that i need I called the .hide()
of the dialoag that I have created. And in this way it goes as it should go.
I ask if is this not a bug?
