(But it seems you already knew that. :-) I know it can be difficult/impossible. By the way, I am coding in Linux, but want my code to be portable between Windows and Linux(!). I will rethink the whole issue. May be I will use the time.sleep alternative, taking a good margin to manage the uncertainty of the delay. -- http://mail.python.org/mailman/listinfo/python-list
