Oddities of Tkinter

[tooper]

Tuvas,

I fully agree with Eric's post above. You may additionnaly have to kill
the main window before exit, to avoid a nasty thread related error
message and occasionally some zombie procs:

import Tkinter,atexit
top=Tkinter.Tk()
.../...
atexit.register(lambda top=top: top.destroy())
top.mainloop()
