Hello all.

I have a rather long code and get always a strange error:

can't invoke "event" command:  application has been destroyed
    while executing
"event generate $w <<ThemeChanged>>"
    (procedure "ttk::ThemeChanged" line 6)
    invoked from within
"ttk::ThemeChanged"


The code is too long but I found some other code that produces exactly
same type of error (see below).

Does anybody have an idea what can be done in this case? Thx for
some help.

Frank.

I use: Ubuntu 10.10, 64 bit, Tkinter, Python 2.6, etc ...
