I thought that it is not allowed to create a new thread after Tk was started because this would then make the SW unstable and possibly crashing

When you create a new thread, it gets a copy of the state of the thread it is created from.

If you create your work thread before creating your tk gui, it does contain any of the gui stuff.

If you then create another new thread from within that first thread, it also will not have any of the tk stuff that you created in the main thread after you started the work thread.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
