Based on the code provided:

tkinter and tkinter.ttk have lots of overlapping classes, like Label, Button, Frame. I'm not sure it's a good idea to mix them with the wildcard import *. Try instead:

import tkinter as tk
from tkinter import ttk

Based on expected problems:

Could you clarify:

• What happens to the root after root = Tk()?
• Do you ever pack the page1?
• Are the buttons packed properly?

Also, do you think there is a problem with style? (Based on the code you've chosen to show). Sorry, can't comment under the posts yet, so decided to answer instead.
