9S12DJ64 reset vector table programming

I'm unable to program the reset vector table on my 9S12DJ64.  I'm using D-Bug12 version 4.0.0b32 and it shows my target as the following, straight out of reset:


Device: S12DJ64, MC9S12DJ64, MC9S12D64, MC9S12A64
EEPROM: $0000 - $03FF
Flash: $8000 - $BFFF  Pages: 4  PPAGE at: $0030
RAM: $0000 - $0FFF
I/O Regs: $0000 - $03FF
Target Speed: 16000 KHz


I see that the vector table area ($FF80-$FFFF) does not appear in the Flash space.  Attempts to fload my s-records into that space fail.  The manual for the 9S12DJ64 says that the reset vector table is available out of reset without setting PPAGE, yet I cannot seem to access and program the table.


Any ideas on what I might be doing wrong?
