No problem - it's all under control. What you are seeing is a perfectly capable system acting in an entirely reasonable manner to an 'undesired perturbation. What may appear to be 'spinning out of control totally' is just dealing roughly with the nuisance that it stops being an issue - either by learning to adapt and become part of the system or being eliminated to an extent where it's adverse effects are suitably mitigated. ie Gaia will get you if you don't behave !!! :-) R :-) M -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
