Sorry to bother you that much. I know I have a lot to learn yet but I hope you can teach me.
I see that someone posted something about running functions with a timer. How can I do this???
I tried to emulate this with the function time.sleep(sec) but all widgets gets locked and they don't refresh themself until the sleep goes off.
Thanks in advanced for the help
