OK, then we probably have either partial chip protection (by setting some bits in the chip) or partial mapping.
Is this an SPI part? Pretty much all recent SPI parts have block protect bits in the status register. The "blocks" are usually some fraction of the part. Many of the parts come with the BP bits set by default and others are non-voltile so a factory setting would stick.
No, it's the PLCC32 revision. It's strange that it seems to work for Ward. Ward, which board revision do you have? (But Ward's board showed some prefered behaviors already without setting the GPIO at all, when flashing sometimes worked for him... ;-))
