Hope that helps.
Annihilannic,

I appreciate the response, and it's good to know I'm not alone with the problem, but I'm writing this for what could be many boxes, including production servers where perl wont be available. That is of course secondary to the fact that there is already a tool that, as far as I know, should work fine. Apart from your workaround, did you find any information on *why* it might be happening?

Thanks again for your time.

Regards,
Mitch.
