[Tkinter-discuss] why this prog.py crash on win32 ?

[francesco.grillo at ciaolab.com]

Hi guys,
i am very surprised how this simple program can hung python (TCL/TK) .
It works fine on a linux system but under windows not .
Can anyone explain why and eventually which by pass apply ?
If i want to write an aplication with a specialized thread that handles

the graphic and that is different than the mainloop what i have to do ?
thanks in advance , Francesco .
