TKinter CheckButton not updating after Button.configure(state=normal)

I'm having trouble with tkinter check boxes updating after enabled/disable:

edit: full, running code detailing the issue. Sorry for not prepending that I had more or less psuedo code before

from tkinter import Tk, ttk, font, PhotoImage, filedialog, END, DISABLED, NORMAL
from tkinter.ttk import *


def subloop():
    for x in range(3, 25, 1):
        boxes[x].configure(state=NORMAL)


boxes = []
root = Tk()
root.geometry("600x500")
root.resizable(False, False)
theme = ttk.Style()
theme.theme_use("winnative")

for x in range(0, 25, 1):
    boxes.append(Checkbutton(root, state=DISABLED))
    boxes[x].place(x=50, y=50 + (15 * x))

root.after(0, subloop)
root.mainloop()

When I remove the theme.theme_use("winnative") line, your code works perfectly. The code even works perfectly, just the way it should when removing that line.

One problem could be that the winnative theme is not scalable. If we replace it with a scalable theme, like this: 

from tkinter import Tk, ttk, font, PhotoImage, filedialog, END, DISABLED, NORMAL

def subloop():
    for x in range(3, 25, 1):
        boxes[x].configure(state=NORMAL)


boxes = []
root = Tk()
root.geometry("600x500")
root.resizable(False, False)
theme = ttk.Style()
theme.theme_use("vista")
for x in range(0, 25, 1):
    boxes.append(Checkbutton(root, state=DISABLED))
    boxes[x].place(x=50, y=50 + (15 * x))

root.after(0, subloop)
root.mainloop()

We replaced the winnative theme with the vista theme. The result is one that is desirable.

Hope this helps!

Edit

We also need to remove the from tkinter.ttk import *. This will make the checkbuttons pure tkinter, instead of ttk.

To anyone seeing this issue as well, removing the "from tkinter.ttk import * " made it so that the Checkbutton was from base tkinter, not tkinter.ttk

from tkinter import Tk, ttk, font, PhotoImage, filedialog, END, DISABLED, NORMAL, Checkbutton


def subloop():
    for x in range(3, 25, 1):
        boxes[x].configure(state=NORMAL)


boxes = []
root = Tk()
root.geometry("600x500")
root.resizable(False, False)
theme = ttk.Style()
theme.theme_use("winnative")

for x in range(0, 25, 1):
    boxes.append(Checkbutton(root, state=DISABLED))
    boxes[x].place(x=50, y=50 + (15 * x))
    boxes[x].deselect()

root.after(0, subloop)
root.mainloop()
