Problem with Tkinter on Mac OS X

[Jean Richelle]

Hello,

I installed version 2.4.1 (and I tried also with 2.4.3) of Python  
under 10.3.9 (and 10.4.6), and I trying to use Tkinter.  For  
simplicity I'm testing the "hello world" that I found in the  
documentation.
I first launch IDLE,  write (cut and paste from the web) the program  
in an editing window, save it, and then run it. The window with two  
buttons is displayed in the back of the IDLE window (and I cannot  
bring it to the front), and there nothing happening when I click  
either button.
Did anybody do a fresh install recently and can run program using  
Tkinter ?
