Yacine, I didn't run it from Idle . I don't use Idle ! I wrote my own IDE when I first started programming in Python, that is what I used(it does execute scripts from the shell ;) What you are seeing is exactly what I was talking about threads and.. dare I say it... bugs ..... Be sure to look at the post on c.l.py that were marked 'Problem in threading'. I am probably wrong , I am not a thread expert by any means, but I think that you are having a problem with the fact that threads can return out of order. Different OSes handle it differently. As always take it all with a grain of salt, and read more docs. Check into queue it is in the standard lib. By the way, I reread your post and still think that threads are not the way for you to go you really need to search for 'python MVC'. It may just enlighten you. M.E.Farmer
