Here is a minimalistic example with a red Frame in a blue window: import tkinter as tk root = tk.Tk() root["background"] = "blue" frame = tk.Frame(root, background="red") frame.grid(row=0, column=0, sticky=tk.NSEW) root.rowconfigure(0, weight=1) root.columnconfigure(0, weight=1) root.mainloop() When you run it as is you should see the red frame. When you remove the lines root.rowconfigure(0, weight=1) root.columnconfigure(0, weight=1) you should see the blue window instead. When you put those lines back in, but change the line frame.grid(row=0, column=0, sticky=tk.NSEW) to frame.grid(row=0, column=0) you will also see blue. So my crystal ball says that in the code that you don't show you forgot to make the Frame "sticky". -- https://mail.python.org/mailman/listinfo/python-list
