Humm. Well, not sure exactly what that tells us,
but my guess (having tried to do this a time or
two myself) is that the calculation of some internal
pointer is off. If my experience is any indication,
off by 1. :-(

My theory is that by writing the file differently,
the pointer was calculated differently in the code.
Good as any, I guess. :-)

Cheers,

David
