I am launching IPyhton with the -q4thread-option. I run a startup-script 
which is building the widget, connecting the signals (e.g. the timer for 
the automatic update) and showing the corresponding widget in the end.

But all the signalling etc. should then run in the separate q4thread, or 
am I wrong?

I can, but that could take some time. Will try.
