Using IDLE!
Try saving your program into a file and running it from the 
DOS prompt - or double clicking it in explorer).

IDLE is written in Tkinter and its difficult for Tkinter to run 
two programs at the same time, it gets confused. There is a fudge 
to get round this but then your program doesn't run right outside IDLE!

Its easier IMHO to just get into the good habit of saving your Tkinter
code as a file and running it outside IDLE. I discuss this issue in 
passing in the GUI section of my tutorial...
