Thanks for the reply. I'm not so familiar with python so could you explain me how to use and become the exception traceback. I've tried today to read something for the beginners about traceback and stack trace in the forum, but I haven't found something really understadable for met. Some piece of code for my case will help :) and I want to learn it of course. Thanks. Boris
