[RobotTech]

def grab_mouse1 ():
	try:
		with Listener(on_click=on_click,on_scroll=on_scroll) as listener:
			listener.join()
	except:#<----
		print("exception on the listener mouse1")#<----
	finally:#<----
		listener.stop()#<----
	global left
	left = window_width
	global top
	top = window_height
	print('value1 x: {0} and value1 y: {1}'.format(window_width,window_height))
	lbl_topleft = tk.Label(root, text = 'Mouse clicked at (x:{0} and y: {1})'.format(left, top), fg = 'green', font =('helvetica', 12, 'bold'))
	canvas1.create_window(150, 200, window = lbl_topleft)
#when button 2 pressed listen to mouse input, when mouse input stop output to label 2
def grab_mouse2 ():
	try:
		with Listener(on_click=on_click,on_scroll=on_scroll) as listener:
			listener.join()
	except :#<----
		print("exception on the listener mouse2")#<----
	finally:#<----
		listener.stop()#<----
	
	global right
	right = window_width
	global bottom
	bottom = window_height
	print('value2 x: {0} and value2 y: {1}'.format(window_width,window_height))
	lbl_bottomright = tk.Label(root, text = 'Mouse clicked at (x:{0} and y: {1})'.format(right, bottom), fg = 'green', font =('helvetica', 12, 'bold'))
	canvas1.create_window(150, 220, window = lbl_bottomright)

by modifying my try/exception function to have finally I have handled the unresponsive but not the exception. the result is the same but i would like to not have the exception.
so my self declared error was reduced to a warning but we are shooting for 100/100 here

Please let me know what you think, Thank you for your help
