Hi Lion, At least under my Windows version running Python 3.3.0rc2, and TK 8.5, I get the initial window is tight to the Entries (no extra space).
However, when I drag the window larger than this minimum, yes, the second row of entries is spaced down from the top one. Three changes to your code: 1) I dropped the last frame, which being empty and without specified dimensions, does nothing. 2) I set the background color of your frames so I can see which frame is actually consuming what space. 3) I changed the expand=1 for the frames to expand=False, and now all frames stick to the top, which is what I think you want. See code below: from tkinter import * t = Toplevel(bg="blue") lbl = Label(t, text="XXXXXXXXXXX") lbl.pack(side=TOP, anchor=N) f1 = Frame(t, bg="green") f1.pack(side=TOP, expand=False, fill=X, anchor=N) e11 = Entry(f1) e11.pack(side=LEFT, expand=True, fill=X, anchor=N) e12 = Entry(f1) e12.pack(side=LEFT, expand=True, fill=X, anchor=N) f2 = Frame(t, bg="red") f2.pack(side=TOP, expand=False, fill=X, anchor=N) e21 = Entry(f2) e21.pack(side=LEFT, expand=True, fill=X, anchor=N) e22 = Entry(f2) e22.pack(side=LEFT, expand=True, fill=X, anchor=N) Now, as to why expand=False, fill=X gives the behaviour you want, I cannot help you. I just much around with these until I find the soultion. Sorry.
