How to manually abort/stop (I call this KeyboardInterrupt) the execution of a Python3 script, using Spyder??

When I click run file or run current cell , nothing can stop the execution of a script until it is finished.

Python 3.7.0 64-bit, Qt 5.9.6, PyQt5 5.9.2, Spyder 3.3.4, Anaconda 3 64bit, Windows 10 64bit

Ctrl + C doesn't work, Ctr+X doesn't work, The red "stop the current command" button in IPython console doesn't work.
The only way I can stop a running script is by menu Consoles> Restart kernel.

This example code shows that KeyboardInterrupt doesn't work in Spyder, in none of the 3 sections below.

def hello():
    print('Hello Spyder '+str(nr))
import time
nr = 0
while nr < 42:
    nr +=1
    hello()
    time.sleep(1)    
#%% loop in function
def hello(n):
    nr = 0
    while nr < n: #n is a local variable, thus not shown in Variable explorer
        nr +=1 #nr is a local variable, thus not shown in Variable explorer
        print('Hello Spyder '+str(nr))
        time.sleep(1)
    return n
import time
x = hello(42) #
#%% just a simple loop
import time
nr = 0
while nr < 42:
    nr +=1
    print('Hello Spyder '+str(nr))
    time.sleep(1)
No errors, but the loop just keeps on executing until it is finished.
Ctrl c  (not capital c) produced the keyboard interrupt for me.  Spyder 3.3.6
Python 3.6.8 64-bit | Qt 5.9.6 | PyQt5 5.9.2 | Windows 10

    while nr < 42:
        nr +=1
        print('Hello Spyder '+str(nr))
        time.sleep(1)
Hello Spyder 1
Hello Spyder 2
