[Tkinter-discuss] Threading issue with Tkinter Frame.insert

[Moray Grieve]

The code fragment below has an example where a Tk GUI is launched as a
separate thread - this all works fine in Python 2.5, but in Python 2.6
the thread hangs. The issue seems to be in the line;

 

self.messageBoxDetails.insert(INSERT, "Hello world")

 

Comment this line out, or use an empty string rather than "Hello World",
and the example works in both Python 2.5 and Python 2.6. I have not been
able to see any related issues to this and wonder if this is a bug in
the 2.6 Tkinter module?

 

Thanks for any assistance.
