I meant there was the main app and one thread. The problem
does not occur when there are no threads running and the app
has to exit.

Very likely - it has happened before :-)

That is what it looks like to me. It seems that the interpreter
is trying to delete a non-existant thread

This will be difficult to do...but perhaps if I give a summary:
def main():
...initialize/configure
...wait for certain events
...based on events launch appropriate thread as follows:
thread.start_new_thread(event_module.run, (StateValues, (job_parms)))
...
def event_module.run(StateValues, (job_parms)):
...initialize/configure
while (1):
Return = os.system(RunString)
if Shutdown flag exists: #thread detects here if needs
to exit
save_job(parms)
cleanup_exit(message, exit_code)
if Return == 0: # SUCCESS
break
elif Return == 1: # ERROR
...
elif Return == 7: # ERROR
...
def cleanup_exit(message, exit_code):
remove temp files
log message, etc
return
So at shutdown, any threads running save their state to a job file
then simply do a return.
Hope this helps...also I use command line apps to program like Nedit.
Know of any visual python debuggers? I know there is "idle"...
any others, better ones?
Have you heard of "eric" python ide. Is it good? - it would have debug
capabilities but is dependent on many libraries I think.
thanks a lot.
