Comment:
Please provide more detail. What code do you use to start a thread? Does that code run correctly when using the command line interpreter (python.exe)? What kind of message do you get from the crash?

Comment:
Under Win98SE, I don't see a crash but a hang is very easy to provoke (the bug report is unclear about which is happening). For example:
def f():
for i in range(100): print "hi", i
import thread
thread.start_new_thread(f, ())
From within IDLE, this freezes solid after a "random" number of prints, and whether typed in directly or run from a file ("Run script" from IDLE Edit menu). Have to kill the shell from the Task Manager.
A possibly different symptom can be provoked by typing
from test import test_thread
from the IDLE prompt.
I don't think this is anything new; I always figured that threads & IDLE don't mix, and never thought more about it.

Comment:
sorry that my comment was not clear enough. my prog works when it's running under the command line interpreter. there's no error message, it just hangs.
here's my code:
from threading import *
class MyThread(Thread):
def __init__(self, aData):
Thread.__init__(self)
self.mData=Data
def run(self):
for i in range(10):
print self.mData
if __name__=="__main__":
aThread=MyThread("Test")
bThread=MyThread("another")
aThread.start()
bThread.start()
aThread.join()
bThread.join()
that's it. we did this at school and my system is a Dual Pentium II with 2 x 400 Mhz and 256Mb.
