Hi there, when executing the standard python example for Timer my python shell freezes after giving out 'hello' and has to be killed. What am I doing wrong!? --code-- import threading def hello(): print "hello, world" t = threading.Timer(30.0, hello) t.start() # after 30 seconds, "hello, world" will be printed --code-- I'm on a WinXP System Regards, Riad
