Query : sys.excepthook exception in Python

[Pramod TK]

Hi,
Sometimes during execution of python scripts below mentioned error string is 
displayed on the console.
"Unhandled exception in thread started by Error in sys.excepthook:
Original exception was:"
The scripts are not terminated, they continue to execute normally.
Is this is a problem with python? Is there any known solution.
I am using Python 2.4.
Thanks in Advance

With Best Regards,
Pramod TK
