Threading Problem

[Norbert]

Thanks a lot, Steve, for your fast reply.
But the behaviour is the same if 'threadfunction' sleeps longer than
just 1 second. 'threadfunction' is of course a dummy to show the
problem, imagine a longrunning background-task.

If you are right, the question remains 'How can I assure that the
starting function finishes, while the other thread still runs ?' .  As
I said, this is the purpose of threading.

Thanks again
Norbert
