<br><span>This is part of a larger project - changing to PyQt5 is probably not a possibility.<br>
<br>Maybe I should add:<br>Everything is fine on the machines of other colleagues, while things go wrong on my and on a second machine.<br>
I checked though that all machines are running the same python & pyqt versions and they all are windows 7...<br>
