Yeah, Nothing is perfect. I can control the damage as long as I know 
what is going on. I guess this would fit in a faq list quite well.

I would have to thank Mike and Dan for your quick and detailed reply. As 
a matter of fact, this python list is the most friendly mailinglist I 
have ever joined. Thanks!
