Tkinter window title won't change

[Michael B.]

Hi!

I have a problem with Tkinter. I am using Python 2.2 with Tkinter Revision 
1.160 on SuSE Linux 8.0 with Kernel 2.4 and KDE3.
The problem is that I can't change the title of any of my Tk()-windows. I 
tried
root.title="Test" and
root.wm_title="Test", as well as 
button.master.title="Test",
but none woud actually change the title. I searched Google, but I only found 
a threat asking the same question without getting an answer.

Thanks in advance,

Michael
