Thanks for the help in advance.

you are closing the application rather than a window. You need to call destroy on the individual window you want to close. The easiest way to do that in your situation is with a lambda:

B5 = tk.Button(DicWin, text='quit', command=lambda win=DicWin:win.destroy)

You should be able to get by with the less confusing:

    B5 = tk.Button(DicWin, text='quit', command=lambda :DicWin.destroy)

But, it is always good to be careful. Depending on what you end up doing down the road, that could cause very confusing errors for a newbie (see here, and here).

You can then get rid of your close_window function.

Edit:

Correction per @fhdrsdg below -- no need for lambda here:

    B5 = tk.Button(DicWin, text='quit', command=DicWin.destroy)

When you use a lambda, you need to actually call the function in the lambda, so using `command=lambda: DicWin.destroy()`. However, since you're not passing arguments to the function, there's no need for the lambda. Just use `command=DicWin.destroy`. — fhdrsdg, Apr 23 '15 at 20:42
