Thank you very much for your answer. It also came to my mind to
separate each loop in it's own thread. But I am for a way from being a
professional in that topics.

I created a minimal working example to ask that question on
StackOVerflow, too. There is no multithreading in that example.

Now I modified that example "based" on your solution. But the GUI is
still freezing why my tasks are working. Your solution is a bit to
complex for me and use some technics (the server think) I don't know.

Could you please throw an eye on the current state of my code?
