[Tutor] Python tkinter. Opening another script from main window stop main window from functioning. Looking for Help

[Spencer For Friends]

Hi all. I'm new to Python and I'm trying my best to learn, but I'm really
struggling with some problems.

I'm using a tkinter window with a button on it to open another Python
script. When the button is clicked and the new script loads it opens up
it's own window over top of my tkinter window. The problem is, when I
switch back to my tkinter window, none of the buttons are click-able
anymore. The whole windows is unresponsive. The click animation on the
button doesn't even function. Any help to resolve this would be greatly
appreciated. Here is my code.


from Tkinter import *
from PIL import ImageTk, Image
import os
from magicassistantcsv import MagicAssistantCSV

CSV_FILE = "data/inventory.csv"
csv = MagicAssistantCSV(CSV_FILE, append=True)
root = Tk()

#Add POP Logo Image To Screen

POPimg = ImageTk.PhotoImage(Image.open("images/poplogo.png"))
panel = Label(root, image = POPimg)
panel.grid(row=0, column =0, sticky=W)

#Add Magic Logo Image

mtgimg = ImageTk.PhotoImage(Image.open("images/mtgcardbot.png"))
panel = Label(root, image = mtgimg)
panel.grid(row=1, column =0, sticky=W, padx=300, pady=180)


#Make Window Full Screen

w, h = root.winfo_screenwidth(), root.winfo_screenheight()
root.overrideredirect(1)
root.geometry("%dx%d+0+0" % (w, h))

#Add Execute Functionality To Button

def callback():
    execfile("test.py")

def endTrade():
    csv.close()


button1 = Button(text = 'Scan Your Card!', font=('Arial', '20'), fg =
'red', command = callback)
button2 = Button(text = 'Scan Complete', font=('Arial', '20'), fg = 'red',
command = endTrade)

#Configure Button Sizes

button1.config( height = 3, width = 25 )
button2.config( height = 3, width = 25 )

#Display Buttons On Screen

button1.grid(row=1, column=0, sticky = S, padx=616)
button2.grid(row=2, column=0)

root.mainloop()

Kind Regards
