Are you using the Numeric package? I've never seen behaviour like that.
1. are you using Numeric or array?
2. how are you reading them in?
3. how are you calculating them? Numeric math ops or explicit loops over
4. could something be keeping a reference to the arrays?
5. what OS are you on?
6. version of python?
Sorry, I think we all need a bit more information to answer you.
