I tried this, but it panics in the same way when running tk.Label(). Again,
I can see an empty window after "root=tk.Tk()".

Sure, I can try with some other combinations of python/tk versions.
However, I tried on other SL6 machines, they have the same version (SL6.5),
and same tests work on those systems. So, the python/2.6.6 and tk-6.5.7
should work...

I can't recall how I set up these systems differently, but I am worried
that there are other non-tk/python related issues... I am just curious if
there are other ways to debug this other than python gdb?

Thanks again for your help!

Kai

You said you tried 2.7.5. I believe 2.7.6 has some tkinter bug fixes.<br>
There is also the issue that TkVersion =3D=3D 8.5 is underspecied -- there =
are multiple bugfix releases. The 2.7 Windows installer has been installing=
 8.5.2, which has some bugs, but 2.7.7 will install 8.5.13, which is much b=
