Hello, The example on how to use the signal module at the bottom of paragraph 17.4 in the Python documentation (see: http://docs.python.org/library/signal.html#signal.SIG_DFL) does not work. This is the error I keep getting: AttributeError: 'module' object has no attribute 'SIGALRM' I'm still quite new to Python, so unfortunately I don't have any suggestions on what should be changed. I'm sorry about that. kind regards, Doris _________________________________________________________________ Alles wat je wilt weten over Windows 7, en meer ! http://www.windows.nl/windows7
