[Ubuntu] PyQt5

[Andrew Diamond]

Hi!

I'm fairly new to Python, and installed pyqt5 and began working through the examples at http://zetcode.com/gui/pyqt5/menustoolbars/  However, whenever I click one of the buttons or menus in the example apps I run that is supposed to quit the application, it locks up.  This happens with all the examples I installed that handle code to quit the app.

Running Ubuntu 15.10, and installed pyqt5 via:

sudo apt-get install python3-pyqt5
sudo apt-get install qtcreator

Thank you in advance for any assistance!
