You're probably not updating after the focus_set.
Try the following:
from Tkinter import *
r = Tk()
def click():
t = Toplevel(r)
e = Entry(t)
e.pack()
b = Button(t, text='Close', command=t.destroy)
b.pack()
e.insert(0, 'Default')
e.select_range(0, END)
e.focus_set()
r.update()
b = Button(r, text='Press', command=click)
b.pack()
r.mainloop()
