That's strange. 

If you ran the script in Idle, try again from the commandline.

You can mix pack and grid for one window, but you have to pick one layout 
manager per parent widget:

top = Toplevel(root)

panel = Frame(top)
panel.pack(...) 
# we picked pack() and now have to use it for all
# children of top
canvas = Canvas(top, ...)
canvas.pack(...) # must use pack() again

# we are free to pick a layout for panel
ok = Button(panel)
ok.grid(...)
# we picked grid() and now have to use it for all 
# children of panel
cancel = Button(panel)
cancel.grid(...) # must use grid()
