What is 'it'?  And what does 'lock up' mean?  Did the gui freeze and not 
disappear?  Or did IDLE itself freeze, and even the menu quit working?

I am an IDLE maintainer.  Am I to take it that everything ran fine 
before you tried to quit?  If not, I would want to know why and try to fix.

If you run tut.py from an IDLE editor, IDLE tries to run it the same as 
if you ran it at a console in the tut.py directory with 'python3 -i 
tut.py'.  I can imagine that there might be a problem with the 
transition from gui mode to interactive shell mode, though it works for 
tkinter apps.  You said 'python3 tut.py' works.  What happens if you add 
the '-i' option?  I'd like to know if the transition problem is in 
(Py)qt5 or in IDLE's simulation of '-i'.
