I have a program that captures all key presses using pyHook, then runs a few functions.
I notice that after a while (of random duration), the program was stop receiving key triggers, even though I am pressing keys?
Is pyHook unstable?
I’m not changing what keys are pressed or pressing them prematurely or anything like that.
Here’s my code:

import time
import win32api
import win32con
import pythoncom
import pyHook
import os
import ctypes

def Click(x,y):
    win32api.SetCursorPos((x,y))
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,x,y,0,0)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,x,y,0,0)

def DeleteRun(event):
    if event.Ascii == 96:
        BreakHook()
        return False
    Click(1250, 741)
    time.sleep(0.2)
    Click(649,261)
    time.sleep(0.2)
    Click(651, 348)
    time.sleep(0.2)
    Click(800, 442)
    time.sleep(0.2)
    Click(865, 612)
    time.sleep(0.2)
    Click(25, 744)
    time.sleep(3)
    Click(25, 744)
    time.sleep(1.5)
    Click(1112,297)
    Click(145,392)
    return True

def BreakHook():
    ctypes.windll.user32.PostQuitMessage(0)

KeyGrabber = pyHook.HookManager()
KeyGrabber.KeyDown = DeleteRun
KeyGrabber.HookKeyboard()
pythoncom.PumpMessages()

Why does is suddenly stop working?
It’s very frustrating as the process remains active on my computer, even if I stop the program through the IDE.
